A) eye
B) leg
C) stomach

On the basis of speed of shortening or contraction, there are slow fibres and fast fibres. The difference in speed of these fibres reflects how fast their myosin ATPases split ATP. (i) Smooth multiunit muscles in intrinsic eye muscles show very slow contraction. (ii) Cardiac muscles in walls of heart show slow contraction. (iii) Skeletal muscles are attached to bones or to skin and show slow to fast contraction.
