Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Understanding the question.
The question asks to match the dentition type of Bivalvia with the corresponding genus. Each type of dentition corresponds to a specific structural feature in bivalve shells.
Step 2: Analyzing the options.
(A) Taxodont - Nucula: Correct — Taxodont dentition is characterized by a large number of small teeth along the hinge, as seen in the genus Nucula.
(B) Isodont - Spondylus: Correct — Isodont dentition involves few, large teeth, seen in the genus Spondylus.
(C) Pachydont - Hippurites: Correct — Pachydont dentition has large, strong teeth, as seen in the genus Hippurites.
(D) Desmodont - Mya: Correct — Desmodont dentition is characterized by a specialized arrangement of teeth, as seen in Mya.
Step 3: Conclusion.
All options are correct, as they match the dentition types of Bivalvia with their corresponding genera.
