Our chemistry teacher taught us how, through a chemical reaction, milk ________ into curd.
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. converts.
The sentence refers to a chemical reaction that causes milk to change into curd. The correct verb should reflect this transformation or change in form.
Progresses – means moves forward or advances, but it doesn’t express change from one form to another.
Converts – means changes something into a different form, which is exactly what happens when milk turns into curd through a chemical reaction.
Diverts – means changes direction, which is not applicable to a chemical reaction.
Happens – is vague and doesn’t fit grammatically in this context. We say “a reaction happens” but not “milk happens into curd.”
