Explanation:

A disadvantage of using stock options to compensate managers is that it can create an incentive for managers to manipulate information to prop up a stock price temporarily, giving them a chance to cash out before the price returns to a level reflective of the firm's true prospects.

A stock option is a contractual agreement that gives a buyer (investor) the right but certainly not an obligation to buy or sell a stock at a specified price and date, depending on the options' form. Generally, in business finance there are basically two (2) types of options;

1. Puts: it is a bet that a stock will likely fall in the short or long run.

2. Calls: it involves betting that a stock will rise in the short run or long run.

Hence, if managers are compensated with a stock option it gives them the opportunity to cash out early.
