Correct option is C
✅ (c) Now we shall not go there unless we are asked:
· This sentence correctly uses the conditional structure "unless we are asked," which means “if we are not asked, we will not go.”
· It is grammatically correct and clearly conveys the intended meaning.
❌ (a) Now we shall not go there unless we shall be asked: Incorrect use of “shall be” in the conditional clause; it should be “are asked.” ❌ (b) Now we shall unless we shall be asked not go there: Incorrect word order, making the sentence confusing and grammatically incorrect. ❌ (d) Now unless we shall be asked we shall not go there: Awkward structure; “shall be” is incorrectly used here.
