A man of letters means a person who is highly educated and skilled in literature. This answer is correct because the expression has a fixed figurative meaning in English. In an SSC idiom question, students should match the whole phrase with its accepted meaning rather than translate each word separately.

• Classroom example: A man of letters can refer to a person who is highly educated and skilled in literature.
• Story example: A writer may use A man of letters when describing a person who is highly educated and skilled in literature.
• Exam example: When a sentence contains A man of letters, choose the meaning “a person who is highly educated and skilled in literature.”
