B

Explanation:
Extrinsic rewards are tangible rewards provided by an external source, typically the employer, such as performance-related pay, holiday entitlement, or company benefits. Intrinsic rewards, however, come from within the individual, such as a sense of achievement, recognition, or responsibility. Option B, recognition, is an intrinsic reward because it relates to personal satisfaction and internal motivation, not a tangible external benefit. Options A, C, and D are extrinsic rewards, as they are controlled externally by the organization.
