The theory that individuals are motivated by three primary needs: a) existence (basic physical needs), b) relatedness (connection with others), c) growth (personal development). proposed by clayton alderfer, the suggests that when people are frustrated trying to achieve a higher-level need, they can be motivated by lower-level rewards.

The correct answer is: Adlers Erg Theory.

Explanation:

The Adlers Erg theory was proposed by Clayton Alderfer as a compliment or a revision of the Maslow's hierarchical theory of needs.

In Clayton's theory, the needs are grouped into three categories or clusters, Basic needs, relatedness, and personal development.

Individuals have to satisfy the lower level needs to move to higher-level ones. The lower level needs are physical, followed by the need to feel connected with other people and being the higher one the need for personal growth.

When the person is not able to satisfy his/her needs of self-actualization and growth they can experience satisfaction and motivation by the rewards they get when they satisfied the lower-level ones.

In conclusion, the correct answer is: Adlers Erg Theory.
