What does it mean if someone is described as "timorous"?

Describing someone as "timorous" means that they are timid by nature or exhibit timidity. This term is often used to reflect a person who is fearful, shy, or lacking in self-confidence, especially in situations that may require assertiveness or bravery. The essence of the word is about a disposition that leans towards apprehension or reluctance, therefore revealing an individual’s tendency to be hesitant or fearful in their demeanor.

In contrast to the other options, which suggest qualities of confidence, boldness, or assertiveness, the meaning of "timorous" centers on a lack of these traits. Thus, the correct choice succinctly encapsulates the essence of timorousness, highlighting a person’s inclination toward shyness or fearfulness.
