In the following question, out of the four alternatives, select the alternative which will improve the bracketed part of the sentence. In case no improvement is needed, select "No improvement".
When it comes to health, prevention is better than cure (let’s it starts with sanitation).

Correct option is A

The correct answer is “since it starts with sanitation."
Explanation:
· The phrase "let’s it starts with sanitation" is incorrect because "let’s" is a contraction of "let us," which does not fit in this context.
· The correct choice is "since it starts with sanitation", which means "because sanitation is the first step in prevention."
Why are other options incorrect?
· “assume it starts with sanitation" – Incorrect because "assume" does not logically connect the two clauses.
· “and it starts with sanitation" – Incorrect because "and" does not provide a cause-effect relationship.
· “No improvement" – Incorrect because "let’s it starts" is grammatically incorrect.
Corrected Sentence:
"When it comes to health, prevention is better than cure since it starts with sanitation."
