Answer:
A- When the girl finally woke up, she was hot and thirsty.
Explanation:
An adverb clause is a subordinate (dependent) clause that functions as an adverb in a sentence. These clauses can modify verbs, adverbs, or adjectives. They provide additional information about when, where, why, how, how much or under what conditions the action described in the independent clause takes place. They are introduced by subordinating conjunctions such as <em>when, until, before, once, while, as soon as, if, whether or not, provided, in case, unless, even if, because, as, since, so, wherever, where,</em> etc. In the example <em>When the girl finally woke up, she was hot and thirsty</em>, the adverb clause is <em>When the girl finally woke up</em>, beginning with the conjunction <em>when </em>and providing information about when the action took place.
