Answer: b) Proprioception
Explanation: Proprioception refers to the body's ability to sense the position, location, orientation, and movement of its various parts. Muscle spindles and Golgi tendon organs are sensory receptors that contribute to proprioception. Muscle spindles provide information about muscle length and stretch, while Golgi tendon organs provide information about muscle tension and force. These sensory inputs are essential for controlling movements and maintaining balance.
