Question

Match List-I with List-II

List-I (Common Name)		List-II (Family)
A	Periwinkles	I	Buccinidae
B	Whelks	II	Ampullariidae
C	Shanks	III	Littorinidae
D	Apple snails	IV	Turbinellidae

Choose the correct answer from the options given below:

• (A) - (III), (B) - (II), (C) - (IV), (D) - (I)
• (A) - (II), (B) - (III), (C) - (IV), (D) - (I)
• (A) - (IV), (B) - (II), (C) - (I), (D) - (III)
• (A) - (III), (B) - (I), (C) - (IV), (D) - (II)

Hint:

Remember: Littorinids are Periwinkles, Buccinids are Whelks, Turbinellids are Shanks (like Sacred Chank), and Ampullariids are Apple snails.

Answer 1

The Correct Option is D

Step 1: Understanding the Concept:
Molluscan taxonomy classifies gastropods (snails and their allies) into distinct families based on anatomical and shell features.
Matching common commercial and ecological names with their scientific families is a fundamental skill in malacology.

Step 2: Detailed Explanation:
Let us match each common name with its corresponding taxonomic family:
1. Periwinkles: These are small, intertidal marine snails belonging to the family Littorinidae. Thus, (A) matches with (III).
2. Whelks: These are carnivorous marine snails widely harvested for food and belong to the family Buccinidae. Thus, (B) matches with (I).
3. Shanks: This group includes commercially and culturally important large marine snails like the sacred chank (Turbinella pyrum), which belongs to the family Turbinellidae. Thus, (C) matches with (IV).
4. Apple snails: These are large freshwater operculate snails belonging to the family Ampullariidae (known for being vectors or pests in agricultural fields). Thus, (D) matches with (II).
This matching sequence gives: (A) - (III), (B) - (I), (C) - (IV), (D) - (II).
This perfectly corresponds to Option 4.

Step 4: Final Answer:
The correct option is (D).
