Answer:
c. An NPV profile graph is designed to give decision makers an idea about how a project's contribution to the firm's value varies with the cost of capital.
Step-by-step explanation:
NPV is Net Present Value of a project. It basically calculates the entire return on project. It is the discounted value of the net returns of the project. Its graph basically demonstrates the contribution of the project, and its difference in cost of capital.
It clearly assumes to add value to the company's contributions if it is more than 0, accordingly the returns are more than cost of capital if NPV is more than 0.
