As matched-pair t-test (or paired t-test or paired samples t-test or dependent t-test) is used when the data from the two groups can be presented in pairs, for example where the same people are being measured in before-and-after comparison or when the group is given two different tests at different times.

Here also test will be done on same person first at age of 40 then at age of 60 so its

Paired Samples t test and hence answer is C.
