Select the most appropriate option to fill in the blank by using the correct degree of adjective:
I think the mango is ___ fruit. I can have as many as four at a time.

Correct option is D

The correct option is (d) a delicious.

Explanation:
The sentence expresses a general personal opinion that the mango is a delicious fruit. The speaker is not comparing it with any other fruit (no comparative or superlative context is established). The second sentence — I can have as many as four at a time — reinforces this as a general statement of how much the speaker enjoys mangoes.

The correct structure requires: the mango is + indefinite article (a) + positive degree adjective (delicious) + noun (fruit).

Correct answer – a delicious:
Delicious is in the positive degree, which is appropriate for a simple, non-comparative statement.
(Hindi meaning: आम एक स्वादिष्ट फल है।)
Example: The rose is a beautiful flower.

Explanation of Other Options:

• (a) a hardly delicious – Hardly means barely or almost not; this would mean the mango is barely delicious, which contradicts the meaning (the speaker loves mangoes).
• (b) the more delicious – Comparative degree; requires a comparison with another fruit. No comparison is mentioned.
• (c) the much most delicious – Grammatically incorrect; much is used before comparatives, not superlatives. The most delicious would be grammatically correct, but no superlative comparison is set up in the sentence.
