To calculate the variance of activity H, we need to use the formula:
Variance = (Optimistic - Pessimistic)^2 / 6

For activity H, the values are:
Optimistic = 8
Most Likely = 10
Pessimistic = 12

Using the formula:
Variance = (8 - 12)^2 / 6
Variance = 16 / 6
Variance = 2.67 or approximately 4

Therefore, the answer is C.
