Answer:
B. Project A
Step-by-step explanation:
Coefficient of variation=standard deviation/expected return value
Project A:
Coefficient of variation=$173,000/$310,000= 0.558
Project B:
Coefficient of variation=$413,000/$676,000= 0.611
Project C:
Coefficient of variation=$120,000/$163,000=0.736
Project D:
Coefficient of variation=$101,000/$134,000=0.754
The Project A has the lowest rate of risk per unit of return, hence, it is the preferred choice of investment
