Question

Match the morphological features in Group I with the corresponding taxa in Group II.

Group I	Group II
P. Dissepiment	1. Echinodermata
Q. Delthyrium	2. Trilobita
R. Pygidium	3. Brachiopoda
S. Ambulacrum	4. Anthozoa

• (A) P – 4, Q – 3, R – 2, S – 1
• (B) P – 4, Q – 3, R – 1, S – 2
• (C) P – 2, Q – 3, R – 4, S – 1
• (D) P – 3, Q – 4, R – 2, S – 1

Answer 1

The Correct Option is A

Step 1: Understanding the Features and Matching with Their Corresponding Taxa

• Dissepiment: A characteristic feature of Anthozoa (Group I: P–4). 
• Delthyrium: A feature of Brachiopoda (Group I: Q–3).
• Pygidium: Found in Trilobita (Group I: R–2).
• Ambulacrum: A key structure of Echinodermata (Group I: S–1).

Step 2: Matching the Features Correctly

Using the observations above, the correct matches are:

\[ \mathbf{P–4, Q–3, R–2, S–1} \]

Final Answer:

Hence, the correct option is: (A).
