What activity will create tension in the legs?
a. stretching your legs before a run
b. standing for five minutes
c. pressing a car's accelerator pedal
d. squatting to pet a dog

Honestly, that is difficult to say because tension can be pressure in an area, which can be D, A. Also tension can mean to be stretched tight, which can be D,A. But hold up read the question again carefully, it asked what activity will create tension in the legs, which means it is A, because D really is not an activity.

What are the choices?
