What encompasses controlling one's internal feelings, impulses, and reactions?

The correct answer is self-regulation. Self-regulation refers to the ability to manage one's internal feelings, impulses, and reactions effectively. This involves recognizing emotions and understanding how they influence behavior and decisions. Self-regulation is an essential component of emotional intelligence and allows individuals to respond appropriately rather than react impulsively to situations.

In contrast, self-management typically involves the broader scope of managing time, priorities, and personal effectiveness, although it can include elements of self-regulation. Emotional stability refers to the ability to remain balanced and composed in various situations but does not specifically address the process of controlling impulses or reactions. Self-awareness involves understanding one's emotions and recognizing how they affect thoughts and behaviors, but it does not necessarily include the active management of those feelings.

Overall, self-regulation is specifically focused on controlling internal reactions, making it the most precise choice.
