A tangible and visible reward given for achievement is known as:

A tangible and visible reward given for achievement is classified as extrinsic motivation. Extrinsic rewards are external incentives provided to individuals for accomplishing specific goals or tasks. Common examples of extrinsic rewards include certificates, trophies, money, or other material incentives that can be seen and touched.

The reason this classification matters in the context of motivation theory is that extrinsic rewards can effectively encourage individuals to perform certain behaviors or achieve goals, especially in educational and professional settings. These rewards often serve as recognition of effort and achievement, thereby reinforcing positive behavior.

In contrast, intrinsic motivation is related to internal satisfaction and personal fulfillment derived from engaging in the activity itself, such as a love for learning or personal growth. The option referring to both intrinsic and extrinsic combines these two distinct concepts, making it less accurate for this specific context, which focuses solely on tangible rewards. The term 'expensive' does not apply, as it does not define the nature of the reward itself but rather the cost associated with it, which is not relevant to the definition of intrinsic or extrinsic motivation.
