Deepak has a penchant for fine poetry.

The correct answer is C. liking.

A penchant is a strong liking or fondness for something. In this case, Deepak has a strong liking for fine poetry.

The other options are incorrect because:

• A desire is a strong feeling of wanting something. Deepak may desire to read fine poetry, but he also has a strong liking for it.
• A bias is a prejudice in favor of or against one thing, person, or group compared with another, usually in a way considered to be unfair. Deepak may be biased towards fine poetry, but this is not the only reason why he likes it.
• Training is the process of teaching someone a skill or knowledge. Deepak may have been trained in fine poetry, but this is not the only reason why he likes it.
