Answer:
b. Only incremental cash flows, which are the cash flows that would result if a project is accepted, are relevant when making accept/reject decisions, is the is CORRECT rule for capital budgeting analysis.
Explanation:
Incremental cash flow is the additional operating cash flow that an organization receives from taking on a new project. The incremental cash flows may be positive or negative.
If it is a positive incremental cash flow, which means the company's cash flow will increase with the acceptance of the project.
If it is negative incremental cash flow, then the company's cash flow will decrease and the project needs to be rejected.
