Explanation:

- Communication: This is the exchange of information. It involves sharing thoughts, ideas, or feelings. It's crucial for interpersonal relationships but not specifically about goal-directed behavior.

- Motivation: This is indeed the process of stimulating people to engage in goal-directed behavior. It involves inspiring individuals to take action towards achieving specific goals.

- Directing: This is more about guiding or supervising someone to reach a certain outcome. It involves giving instructions or orders rather than stimulating intrinsic motivation.

- None of these: This would imply that none of the options fit, which isn’t the case here.
