Answer: (iii) Feeling a sense of accomplishment from completing a challenging task

Justification:

• Intrinsic motivation = Doing work for internal satisfaction inherent in the task itself - not for external reward. (Deci & Ryan's Self-Determination Theory).
• (iii) is intrinsic: Pride, mastery, challenge, personal growth - the reward is the feeling itself.
• Extrinsic examples (others):
  • (i) Overtime for extra pay - monetary reward
  • (ii) Good environment - external working condition
  • (iv) Promotion - status/reward given by organization

Intrinsic	Extrinsic
Achievement, Recognition (internal feeling), Responsibility, Growth	Pay, Bonus, Promotion, Environment, Job security
