Question

iv) You may go home when you have finished.
(Pick out the adverb clause)​

Answer 1

*when you have finished*. This it the adverb clause.

Because an adverb clause (or adverbial clause) is a clause that works as an adverb in a sentence. Its role is to show place, time, condition, degree, and so on, by answering questions like “where?”; “when?”; “how?”; and “why?” Just like an adverb, it modifies other parts of a sentence to add more details.
