a. anyone who has ever climbed a mountain
b. people who have never climbed a mountain
c. the mountain climbers being studied
d. mountain climbers and nonclimbers

Explanation:

The scientist wants to study how thin air at great heights affects people who climb mountains. So the sample group should be the mountain climbers being studied (option C) because A includes non - climbers (anyone who has climbed, but the study is about those affected while climbing), B is people who never climbed (not relevant), D includes non - climbers (mountain climbers and non - climbers, but the study is about climbers). Only C focuses on the mountain climbers under study.

Answer:

C. the mountain climbers being studied
