Step 1: Understand the question.
The question asks for a reward that carries both a money gain and a non-money gain together.
Non-financial rewards include recognition, status, job security and growth. Financial rewards include money, bonus and perks.
Step 2: Apply the textbook example.
The textbook says a promotion into sales management gives a higher salary (financial) and a more respectable position (non-financial).
So promotion is the reward that is coupled with a financial reward.
Step 3: Check option (A) Bonus.
A bonus is only extra money. It has no status or recognition element of its own. So (A) is wrong.
Step 4: Check option (B) Dividend.
Dividend is a share of profit paid to shareholders. It is not a reward given to sales people for performance. So (B) is wrong.
Step 5: Check option (C) Interest.
Interest is the price paid for borrowed money. It has nothing to do with sales force rewards. So (C) is wrong.
Step 6: Check option (D) Promotion.
Promotion brings a pay rise and a higher post at the same time. So (D) is correct.
Final Answer:
Promotion mixes a financial gain with a non-financial gain. This is option (D).
