Out of the given sentences, only one is grammatically correct. Identify the correct sentence. If none are correct, select option (e).

Question

Accepted Answer

**Solution:**

1. Sentence (a) is incorrect because the phrase "capable at offering" is wrong. The correct phrase is "capable of offering".

2. Sentence (b) is incorrect because the subject "policymakers" is plural, so the verb should be "need" instead of "needs".

3. Sentence (c) is incorrect because the noun "leak" should be plural "leaks" to agree with "frequent".

4. Sentence (d) is grammatically correct. It properly uses the singular verb "will ensure" and the phrase "as well as" does not change the number of the subject. The sentence is clear and well-structured.

5. Since sentence (d) is correct, option (e) "None of these" is incorrect.

**Answer:** (d)
