Answer:
3. Incentivizing your employees to work harder
Explanation:
Increasing production is the same as increasing productivity. This measures the ratio of output to input. It can improve by increasing outputs while keeping inputs constant or by reducing inputs while keeping outputs constant. The former applies to this case as the employees provide labour input which is constant but with an aim to increase production. You will therefore choose an option that would result in more output; that is incentivizing your employees to work harder.
