Question

We will leave from here ________. Choose the most appropriate word to fill the blank.
A. after sunset
B. you will stay here
C. as soon as it stops raining
D. tonight

Answer 1

Hint: An adverb clause refers to the group of words that works as an adverb. An adverb clause begins with the subordinating conjunction such as if, although, because, and so forth. Lastly, it includes a subject and predicate.

Complete answer:
Adverb phrase refers to the group of words that qualifies adjectives, verbs, or adverbs. Adjective Phrase refers to the modification of the noun or pronoun in a sentence with group words.
The adverb phrase can be replaced by an adverb clause by changing the subject of the adverb phrase into two same subjects and by changing the -ing form of the verb.

For instance,
Sita came to Germany since then he is increasing his fluency in German. - Adverbial phrase
Its adverbial clause will be,
Since coming to German, Sita has been increasing his fluency in German.

In the given sentence, 'We will leave from here _________' the appropriate adverb clause will be Option C. as soon as it stops raining and option A. after sunset here the adverb clause 'as soon as' and 'after' modifies the verb 'stops raining' and 'sunset'

The other options are incorrect. Let's know why these options are incorrect.
Option B. you will stay here
Option D. tonight
The above options are incorrect as the question has asked to fill the adverbial clause. These two options are not an adverbial clause.

Hence the correct answers are option ‘A’ & ‘C’.

Note: While using the adverb clause we must be careful about the spelling. Also, adverbs indicating frequency comes in the middle of the sentence. Adverbs indicating time are placed at the end of the sentence and we don't use adverbs like usually, always, never, and so forth at the beginning of the sentence.
