Sublimation is best defined as:

Sublimation is a psychological defense mechanism that involves redirecting negative or socially unacceptable impulses into socially acceptable and constructive activities. This process allows individuals to channel their emotions or desires into productive outlets, which can be beneficial for both personal growth and societal contributions. For example, someone experiencing anger might take up a sport or engage in artistic endeavors as a way to express those feelings positively. This transformation not only alleviates the internal tension associated with those impulses but also fosters personal development and social integration.

In contrast, avoiding feelings through distraction, completely suppressing feelings, or expressing feelings through anger do not align with the essence of sublimation. These alternatives suggest a more passive or unproductive approach to managing emotions, rather than actively transforming them into something constructive. Therefore, the choice that describes the redirection of feelings into socially productive activities captures the core of sublimation accurately.
