$\begin{array}{cc}\text{Column 1}& \text{Column 2}\\ \text{P. Crista and macula}& \text{1. Spinal cord}\\ \text{Q. Knee-jerk reflex}& \text{2. Cochlea}\\ \text{R. Scala media}& \text{3. Photoreceptor cells}\\ \text{S. Rods and cons}& \text{4. Vestibular apparatus}\end{array}$

• A. P-1, Q-2, R-3, S-4
• B. P-3, Q-3, R-4, S-2
• C. P-4, Q-1, R-2, S-3
• D. P-3, Q-4, R-1, S-2

Answer 1

The correct option is C P-4, Q-1, R-2, S-3

Crista and macula are the receptors of the vestibular apparatus in the inner ear. They are responsible for maintaining the balance and posture of the body.
Scala media is the space within cochlea.
The knee jerk reflex is a reflex in which there is a sudden kicking movement of the lower leg in response to a sharp tap on the tendon in the knee bone patella. It is controlled by spinal cord.
Rods and cones are two photoreceptor cells present in the retina. Rods are responsible for night vision and cones are responsible for day vision.
