Sagot :
I think the correct answer from the choices listed above is option D. The sentence which contains an adverbial clause is "Most animals thrive where they can find food easily." This sentence shows the way by which an animal finds it food. Hope this answers the question. Have a nice day.
The correct answer is D. Most animals thrive where they can find food easily.
Adverbial clauses act as adverbs - they answer the questions of where, when, why, etc. and always have adverbial functions. This is why A and C are not adverbial clauses - because both clauses have noun functions - both of them are used as objects rather than adverbs. B is incorrect because it is a noun clause, not an adverbial one.
Therefore, D is correct. Here, the adverbial clause is where they can find food easily.
