Answer:
A, C and D
Step-by-step explanation:
A - When you freeze money for future use in an investment project, you are losing money that could be earned doing something else at least until the new project starts (opportunity cost). So instead of freezing money the company should use it for other investments until it is needed.
C - A safe but ineffective way of always being below cost is to overestimate costs. So instead of rewarding employees for performing below cost is to estimate more "real" costs and rewarding employees for performing at the real cost levels.
D - Generally speaking top management receives bonuses when shareholders' wealth is increased, so the same practice can be done with middle management in order to motivate them.
