Select the most appropriate option to substitute the highlighted segment in the given sentence.
Suman felt ashamed and shy about admitting his fault before his boss.

Explanation of the Correct Answer:
· The phrase "ashamed and shy" means feeling guilty, uneasy, or self-conscious about something.
· The best replacement for "ashamed and shy" is "embarrassed," which means feeling awkward, self-conscious, or guilty about something.
Example Sentences:
· She felt embarrassed when she tripped on the stage.
· He was ashamed of his rude behavior in front of his teacher.
Other options:
· (b) "brazen" → Incorrect because "brazen" means "bold and unashamed," which is opposite in meaning.
· (c) "sad" → Incorrect because being "ashamed and shy" is about guilt and discomfort, not just sadness.
· (d) "exalted" → Incorrect because "exalted" means "highly praised or elevated," which is unrelated to feeling ashamed.
Thus, the correct answer is (a) "embarrassed."
