Topic: Pair of Word,

Best Answer Explained in Below-:

In the sentence "Be careful, he is a very ---- man," the correct option is "sensitive" (C). This choice implies that the man possesses heightened awareness or emotional responsiveness, suggesting he might react strongly to external stimuli or emotional situations. The context of warning someone to "be careful" aligns with the idea that a sensitive person might take offense easily or may not handle criticism or tough situations well.

Let's examine the other options:

- **Sensible (A)** refers to someone who is rational and makes wise decisions. While it conveys a positive trait, it does not fit the context of a warning.

- **Sensual (B)** denotes an appreciation for physical pleasures or gratification, typically associated with the senses. This term, while potentially implying a level of risk due to desire, lacks the necessary warning tone for the context given.

- **Sensuous (D)** has a similar connotation to sensual but emphasizes the enjoyment or appreciation of physical sensations, especially in an aesthetic or pleasurable way. It does not inherently convey any threat or warning.

Thus, "sensitive" is the most appropriate word choice, as it accurately captures the essence of caution due to the man's emotional or empathetic nature, which can lead to heightened reactions.
