An individual's personality:

A) changes several times throughout the year.
B) is formed only from childhood socialization and the environment.
C) is less evident in situations where social norms, reward systems, and other conditions constrain behavior.
D) is all of the above.
E) is only 'B' and 'C'

Personality can be less evident in situations where external factors such as social norms, reward systems, and other conditions constrain behavior, as these factors can influence how an individual behaves, potentially masking their true personality traits. Personality is not solely formed from childhood socialization and the environment, nor does it change several times throughout the year. It is influenced by a combination of genetic, environmental, and situational factors.
