Step-by-step explanation:
The word for composure or coolness, especially in trying circumstances, is equanimity. This term describes a person's ability to maintain calmness and control over their emotions regardless of the situation at hand. The correct option in the provided list is c) Equanimity.
Complacency generally refers to a feeling of smug or uncritical satisfaction with oneself or one's achievements, serenity is a state of being calm, peaceful, and untroubled, and audacity refers to the willingness to take bold risks.
Equanimity is a quality that can be found in various contexts, such as in Franklin's thirteen virtues or in discussions about self-possession in the face of disorder and hubbub amongst the enemy.
