B
As the muscle relaxes, collagen fibers 'squeeze' the nerve endings of the golgi tendon organ.
C
As the muscle contracts, free nerve endings in the golgi tendon organ are compressed by muscle fibers.
D
As the muscle stretches, free nerve endings in the golgi tendon organ are compressed by muscle fibers.
