Final answer:
To calculate the coefficient of variation, divide the standard deviation by the expected return and multiply by 100.
Step-by-step explanation:
To calculate the coefficient of variation for each option, divide the standard deviation by the expected return and then multiply by 100 to get a percentage.
Option A: Coefficient of Variation = (6% / 10%) * 100 = 60%
Option B: Coefficient of Variation = (8.5% / 12%) * 100 = 70.83%
Option C: Coefficient of Variation = (3% / 8%) * 100 = 37.5%
Option D: Coefficient of Variation = (9% / 14%) * 100 = 64.29%
