Ditransitive Verbs in Technical English

"Assigned Maria the ticket" is correct: this is the double-object (ditransitive) pattern, where the indirect object ("Maria", the recipient) comes immediately after the verb, followed by the direct object ("the ticket", the thing given). Option A incorrectly inserts "to" before the indirect object in the double-object pattern, which is not permitted in that structure — "to" is only used in the prepositional dative alternative ("assigned the ticket to Maria"). Option C combines two prepositions, "to for", which is ungrammatical and redundant. Option D changes the meaning entirely, implying Maria was assigned to work as though she were the object being placed onto the ticket, rather than receiving it.

"Send the deployment notification to the entire on-call engineering team responsible for the payments service" is correct: when the recipient is a long, heavy noun phrase, English strongly prefers the prepositional dative pattern (direct object first, then "to" + recipient) to respect the end-weight principle and keep the sentence readable. Option A omits "to" while still placing the long recipient phrase second, which is ungrammatical without the preposition in that word order. Option B places the long recipient phrase before the direct object without "the" reordering being idiomatic, producing an awkward, hard-to-parse structure. Option D uses the double-object pattern with a heavy recipient noun phrase immediately after the verb, which is grammatically possible but strongly dispreferred stylistically because it front-loads a very long phrase before the short direct object.

"Granted the new intern's account read access" is correct: this follows the double-object pattern, with the indirect object ("the new intern's account") immediately after the verb, followed by the direct object ("read access"). Option A is actually a valid prepositional dative version ("granted read access to..."), but it is not the double-object pattern the question asks for, so it does not match the required structure. Option C omits the required preposition "to" before the recipient while still using the prepositional word order, making it ungrammatical. Option D incorrectly inserts "to" into what should be the double-object pattern, which does not use a preposition before the indirect object.

"Explained the new caching strategy to the team" is correct: "explain" is one of a small class of verbs (also including "describe", "suggest", "announce") that only accepts the prepositional dative pattern, never the double-object pattern. Option A incorrectly uses the double-object pattern ("explained the team the new caching strategy"), which is ungrammatical for this verb. Option B keeps the correct preposition "to" but places the recipient phrase before the direct object, an unnatural and non-standard order for the prepositional dative. Option D omits the required "to" entirely while still using double-object-like word order, making it doubly ungrammatical for this verb.

"Give it to them once the review is approved" is correct: when the direct object is a pronoun ("it"), English strongly prefers the prepositional dative pattern rather than the double-object pattern, so "it" comes right after the verb and "to them" follows. Option A uses the double-object pattern with a pronoun direct object ("them it"), which is grammatically dispreferred and sounds unnatural in standard English. Option B similarly uses a double-object-like order without "to", which is ungrammatical here. Option D scrambles the order by placing "to them" before the pronoun object "it", which is not a valid English word order for this construction.
