Answer:

Option B, 60,000 years ago

Explanation:

It is given that the rate of substitution is one substitution per 10,000years

Thus, starting from the base year

Number of substitution after 10,000years = 1

Number of substitution after 20,000years = 2

Number of substitution after 30,000years = 3

Number of substitution after 40,000years = 4

Number of substitution after 50,000years = 5

Number of substitution after 60,000years = 6

Thus, it is clear that 6 substitution or changes will occur in 60,000years.

Thus, option B is correct.
