Answer:
Mechanoreceptor and proprioceptor.
Explanation:
Patellar tendon may be defined as the fiber that attaches the patella to the tibia. The tear in the patellar tendon may cause severe injury and cause difficulty in walking.
Mechanoreceptor may be defined as the receptor that activates in response to touch or the mechanical sound. Proprioceptor may be defined as the receptor that respond in the position and movement. The patellar tendon monitors both the proprioceptor and mehanoreceptor.
Thus, the correct answer is option (B).
