Using proportions, it is found that the correct statement is given by:

D. On average, 2 out of 10 adults visited the museum most frequently.

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

In this problem, there is a total of 31 + 14 + 17 + 8 = 70 adults.

Applying the rule of three, 2 out of 10 considering 70 adults is equivalent to 14 adults, hence option D is correct.
