Question

Match List I with List II

List I		List II
A	Pleurobrachia	I	Mollusca
B	Radula	II	Ctenophora
C	Stomochord	III	Osteichthyes
D	Air bladder	IV	Hemichordata

Choose the correct answer from the options given below:

• A. A-IV, B-II, C-III, D-I
• B. A-II, B-I, C-IV, D-III
• C. A-II, B-IV, C-I, D-III
• D. A-IV, B-III, C-II, D-I

Answer 1

The Correct Option is B

To solve the problem of matching List I with List II, we need to correctly associate each item from List I with a corresponding item from List II based on their biological classifications or characteristics:

A	Pleurobrachia	II	Ctenophora
B	Radula	I	Mollusca
C	Stomochord	IV	Hemichordata
D	Air bladder	III	Osteichthyes

Explanation of matches:

• Pleurobrachia is a type of comb jelly, which belongs to the phylum Ctenophora. Therefore, A should match with II.
• Radula is a feature found in Mollusca, providing a way for mollusks to feed by scraping or cutting food. Therefore, B should match with I.
• Stomochord is a structure found in the phylum Hemichordata. It is part of the stalklike projection into the proboscis. Therefore, C should match with IV.
• Air bladder, also known as the swim bladder, is present in fish within the class Osteichthyes (bony fish), helping them maintain buoyancy. Therefore, D should match with III.

Correct match: A-II, B-I, C-IV, D-III

Answer 2

A. Pleurobrachia is a member of the phylum Ctenophora (II).

B. Radula is found in organisms from the phylum Mollusca (I).

C. Stomochord is a characteristic feature of organisms from the phylum Hemichordata (IV).

D. Air bladder is found in fish from the phylum Osteichthyes (III).

Thus, the correct answer is (2) A-II, B-I, C-IV, D-III.
