muscle X and muscle Y are of same size , but muscle X is capable of much finer control than muscle Y . which of the following is likely to be true of muscle X?
1. it is controlled by more neurons than Y.
2. it contains fewer motor units than Y.
3. it is controlled by fewer neurons than Y.
4. each of its motor units consists of more cells than the motor units of muscle Y.

The control and coordination of the muscles is done by the neurons. As, muscle X can be controlled more accurately than the muscle Y, thus it must be controlled by  more neurons than the muscle Y.
