According to the Size Principle:
A)Large α Motor Neurons Are $\gamma$

According to the size principle:

A) Large α motor neurons are recruited before small ones.
B) Large and small α motor neurons are recruited simultaneously.
C) α and $\gamma$ motor neurons are activated simultaneously during a movement.
D) α motor neurons are activated before $\gamma$ motor neurons during a movement.
E) Small motor neurons are more excitable than are large motor neurons.
