Which of the statements correctly describes the difference between forced vital capacity and vital capacity?

a. In forced vital capacity assessment it is essential to exhale as quickly and forcefully as possible.

b. In forced vital capacity the subject is exposed to stress and must exhale when they cannot hold air any longer.

c. Forced vital capacity will typically show a larger volume than just vital capacity.
