Answer: Option (A)
| Year(i) | Beginning Price | Ending Price # | Capital Gain^ | Dividend | Total Return | Returns(Ri) | (1+Ri) | |
| 2015 | $ 118 | $ 126 | $ 8 | $ 3 | $ 11 | 9.32% | 1.0932 | |
| 2016 | $ 126 | $ 110 | $ (16) | $ 3 | $ (13) | -10.32% | 0.8968 | |
| 2017 | $ 110 | $ 115 | $ 5 | $ 3 | $ 8 | 7.27% | 1.0727 | |
| 2018 | $ 115 | NA | NA | $ 3 | ||||
| Sum | 6.28% | Product | 1.0517 | 
| # Ending Price of 2015 will become the Beginning Price of 2016 | 
| ^Capital Gain = Ending Price - Beginning Price | 
| Total Return = Dividnd + Capital Gain | 
| Return = Total Return / Beginning Price | 
Note: Return for the year 2018 is not considered as Year End Price is not given (Due to which Capital Gain Computation is not available)
| Arthematic Mean = Sum of Observations / No. of Observations | 
| Arthematic Mean = 6.28 / 3 | 
| Arthematic Mean = 2.09% | 
| Geometric Mean = [((1 + R1) × (1 + R2) × ... × (1 +Rn))^(1/n)] - 1 | 
| Geometric Mean = [((1 + 0.0932)(1 - 0.1032)(1 + 0.0727))^(1/3)] - 1 | 
| Geometric Mean = [(1.0517)^(1/3)] - 1 | 
| Geometric Mean = 1.017- 1 | 
| Geometric Mean = 1.7% |
