Question

Fill in the blank with the most appropriate word.
Let's stay at home tonight ____ you want to watch TV.

• A. that
• B. since
• C. because of
• D. whether

Answer 1

The correct option is B since

In the given sentence, the answer is connecting two clauses and thus, it must be a conjunction. The sentence indicates that the subject suggests staying home 'because' the object wants to watch TV. Thus, the answer must be a conjunction meaning 'because'.

Option A is incorrect. 'that' is a demonstrative pronoun and not a conjunction. Thus, it cannot be used to connect two clauses.

Option B is correct. 'since', in this case, means 'because'. It is a conjunction that can be used to indicate reason. Thus, it is the correct answer.

Option C is incorrect. In'because of', 'because' and 'of' both act as conjunctions. Thus, the this answer contains two adjacent conjunctions but, only one conjunction can be used to connect two clauses. Thus, option C will make the sentence grammatically incorrect.

Option D is incorrect. 'whether' is a conjunction that is used to introduce alternatives in the sentence. It does not mean 'because'. For example, It does not matter whether we go or stay.
