Final answer:
The term MARR represents the Minimum Attractive Rate of Return, which is the lowest acceptable return rate for an investment, surpassing the threshold determined by the company's or individual's cost of capital and associated risks.
Step-by-step explanation:
The acronym MARR stands for Minimum Attractive Rate of Return. It represents the lowest rate of return on an investment that a company or individual would be willing to accept.
When considering options for investment, any project or investment must have an expected rate of return that is higher than the MARR to be considered viable. The MARR is often based on the cost of capital, risks associated with the investment, and the opportunity cost of forgoing other investments.
Therefore, the correct answer to the question 'What is MARR?' is C) Minimum Attractive Rate of Return.
