To calculate the inbreeding coefficient, we need to use the formula:  F = (1/2)^(n+1)

where n is the number of meioses (generations) from the common ancestor to the individual, excluding any meioses involving inbreeding.

In this case, n=4. So, we have:

F = (1/2)^(4+1) = 1/2^5 = 1/32 = 0.03125

Therefore, the inbreeding coefficient is 3.125%, which corresponds to choice C.
