Question

Which of the following pairs is NOT correctly matched?

• A. Productus - Brachiopoda
• B. Redlichia - Arthropoda
• C. Belemnites - Cephalopoda
• D. Gryphea - Gastropoda

Hint:

When matching organisms, be sure to know their correct taxonomic classification (e.g., Gryphea is a bivalve, not a gastropod).

Answer 1

The Correct Option is D

Step 1: Understanding the classification of organisms.
- (A) Productus is a genus of brachiopods, so this is correctly matched.
- (B) Redlichia is an extinct genus of trilobites, classified under Arthropoda, so this is correctly matched.
- (C) Belemnites are cephalopods, so this is correctly matched.
- (D) Gryphea is an extinct genus of oysters, classified under Mollusca (Bivalvia), not Gastropoda, so this is incorrectly matched.

Step 2: Conclusion.
The correct answer is (D) Gryphea - Gastropoda, as Gryphea is a bivalve, not a gastropod.
