Correct Answer: Monk

Solution : The correct choice is the third option .

A "monk" is a person who lives a secluded or solitary life, often for religious reasons. Monks typically withdraw from the world to devote themselves to their religious or spiritual practices in solitude.

The meanings of the other options are as follows:

• "Extrovert" is the opposite of a person who lives a secluded or solitary life. Extroverts are outgoing and social individuals who thrive in the company of others.
• "Chauvinist" refers to a person who displays excessive and aggressive patriotism or loyalty to his group, which is not related to living a secluded life.
• A "hypochondriac" is a person who is excessively anxious about his health and believes he has illnesses, but this has no direct relation to living a secluded life.
