What does a reward power base allow a leader to do?

A reward power base enables a leader to provide compensatory benefits for achievements, making this the correct choice. This type of power is rooted in the leader's ability to grant rewards, which can come in many forms, such as praise, financial bonuses, promotions, or other forms of recognition. Leaders who utilize reward power effectively can motivate their group members to achieve goals and improve performance, as individuals often respond positively to the prospect of gaining rewards for their efforts.

In contrast to the other options, imposing restrictions on group members relates more to coercive power, which is based on the ability to punish. Leading through dominant authority pertains to positional power rather than reward power; it emphasizes control rather than motivation. Influencing others through visual appeal is tied to referent power, which is based on personal traits and charisma. Thus, the emphasis of reward power is on incentivizing and motivating individuals rather than controlling or influencing them through authority or appeal.
