Which of the following is an example of an investment decision made by a financial manager?

A. Deciding whether to buy back some of the firm's issued shares

B. Deciding whether to pay off an outstanding bank loan

C. Deciding whether to sell an old piece of equipment

D. Deciding whether to issue shares to raise capital

May I ask which one is an investment decision made by a financial manager and why? and should I focus on investment decision factor or financial manager's factor in this question?

Thank you
