Identify the solutions that represent the lowest amount of resources required to achieve each distinct return value. Complete the table below.

Which of the following best describes the best options and trade$-$offs that must be made to increase the returns?

A$.$ In order to achieve a greater return, it is sometimes necessary to increase the cash requirement. However, to achieve the greatest return, only the personnel requirement needs to be increased.

B$.$ In order to achieve a greater return, it is always necessary to increase the personnel requirement. However, to achieve the greatest return, it is also necessary to increase the cash requirement.

C$.$ In order to achieve a greater return, it is sometimes necessary to increase the cash requirement. However, to achieve the greatest return, it is also necessary to increase the personnel requirement.

D$.$ In order to achieve a greater return, it is sometimes necessary to increase the personnel requirement. However, to achieve the greatest return, only the cash requirement needs to be increased.
