Motivation is the reason behind human actions or behaviors aimed at goal attainment.
It can originate internally from a person or externally from outside influences.
When individuals are propelled by their own interests, inquisitiveness, or contentment, it is termed intrinsic motivation.
Conversely, when the impetus stems from external factors such as rewards, bonuses, commendation, advancement, or other advantages, it is identified as extrinsic motivation.
The query explicitly refers to 'incentives or external rewards,' which aligns directly with extrinsic motivation.
Consequently, option (B) is the accurate selection.
