Options:

• A. A-iii, B-iv, C-ii, D-i
• B. A-iii, B-i, C-ii, D-iv
• C. A-iii, B-i, C-iv, D-ii
• D. A-ii, B-i, C-iv, D-iii

Answer 1

The correct option is C A-iii, B-i, C-iv, D-ii

Touch - Sensory papillae

The sensory papillae in frogs are associated with touch.

Smell - Nasal epithelium

Nasal epithelium is a sensory epithelium present in the nose and detects chemical stimuli in the air. Therefore it is associated with smell.

Cranial nerves - Peripheral nervous system

The cranial nerves arise from the brain. In the case of frogs there are 10 pairs (humans 12 pairs) and they along with the spinal nerves form the peripheral nervous system.

Medulla oblongata - Foramen magnum

The medulla oblongata is the last part of the hindbrain and enters as the spinal cord through an opening present in the base of the human skull called foramen magnum.

Column I	Column II
A. Touch	iii. Sensory papillae
B. Smell	i. Nasal epithelium
C. Cranial nerves	iv. Peripheral nervous system
D. Medulla oblongata	ii. Foramen magnum

Final answer: d. A-iii, B-i, C-iv, D-ii.
