The correct answer is A.

Explanation: The statement "The man dies in him who keeps silent in the face of tyranny" is metaphoric because it uses figurative language to convey a deeper meaning. It implies that a person's moral or inner integrity is lost (or metaphorically "dies") when they fail to speak out against oppression or injustice.

Other options:
- B. Literal: The statement is not meant to be taken literally, as no actual physical death occurs.
- C. Tragic: While the sentiment might evoke a tragic feeling, this option doesn't describe the type of language used.
- D. a simile: A simile compares two things using "like" or "as." Since no such comparison is being made here, it's not a simile.

Thus, the statement is best described as metaphoric.
