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

A. He scored 3 under par on each of the first 14 holes and 2 over par on each of the next four holes.

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

His score on the first 14 holes was –42, hence his score per hole was given by:

S = -42/14 = -3.

Final score was –34, hence his score was the last four holes was of:

-42 + x = -34 -> x = 8.

Per hole, the score was:

8/4 = 2.

Hence, considering a negative score is under par and a positive score is over par the correct option is:

A. He scored 3 under par on each of the first 14 holes and 2 over par on each of the next four holes.
