In order for the conclusion to hold valid, that particular artefact has to tie in for the conclusion of the diatonic note dating much earlier. Option D talks about flutes in general and not the...

Avg of 16 student scores = 62.5
Total scores of the 16 students = 62.5 x 16 = 1000
Avg of 15 student scores = 64
Total scores of the 15 students = 64 x 15 = 960
Score of the 16th student = (Total of 16 student scores) - (Total of 15 student scores)
= 1000 - 960
= 40

Hence, the answer is Option C.
