Final answer:
The CFO's presentation regarding the choice between a new delivery truck and a metal stamping press illustrates a decision involving mutually exclusive projects, where only one project can be chosen. Option E is correct.
Step-by-step explanation:
The decision between buying a new delivery truck and purchasing a three-ton metal stamping press represents a choice involving mutually exclusive projects. These are projects where only one can be chosen, as selecting one option precludes the possibility of going ahead with the other.
Factors like cost, potential returns, efficiency, and alignment with the company's strategic goals will play a crucial role in deciding which project to undertake.
