Choose the most appropriate statement in comparative degree from the options provided, for the sentence given below:
Kerala is the greenest state in India.

Correct option is A

The correct option is (a) No other state in India is greener than Kerala.

Explanation:
The original sentence uses the superlative degree: the greenest. To convert this into the comparative degree without changing the meaning, the standard structure used is:

Grammatical Rule (English):

• Superlative → Comparative: No other + noun + comparative adjective + than + subject
• Example: X is the best → No other [noun] is better than X.

• (b) Kerala is much green as any other state in India – Grammatically incorrect; much green is wrong. The correct form is as green as, and this structure represents the positive degree, not the comparative.
• (c) Most states in India are greener than Kerala – This reverses the meaning; it suggests Kerala is less green, which contradicts the original sentence.
• (d) Kerala is as green as any other state in India – This uses the positive degree (as...as structure) and implies equality, not superiority. It does not preserve the original superlative meaning.
