The correct Answer is:
To answer the question "Jaw of shark contains," we will analyze the options provided and identify the correct type of dentition found in sharks. ### Step-by-Step Solution: 1. **Understand the Types of Dentition**: - There are different types of dentition in vertebrates, including thecodont, pleurodont, and acrodont. 2. **Examine the First Option - Thecodont**: - Thecodont dentition is characterized by teeth that are completely enclosed in sockets within the jawbone. This type is typically found in mammals and some reptiles, such as crocodiles. - Since sharks do not have this type of dentition, this option is incorrect. 3. **Examine the Second Option - Pleurodont**: - Pleurodont dentition is where teeth are fused to the inner surface of the jawbone. This type is commonly found in reptiles. - Sharks do not exhibit pleurodont dentition, making this option also incorrect. 4. **Examine the Third Option - Acrodont**: - Acrodont dentition is characterized by teeth that are attached directly to the jaw without sockets. This type of dentition is commonly found in fish and some lower vertebrates. - Since sharks possess acrodont dentition, this option is correct. 5. **Examine the Fourth Option - None of the Above**: - Since we have already identified that sharks have acrodont dentition, this option is incorrect. ### Conclusion: The jaw of a shark contains **acrodont** teeth. Therefore, the correct answer is **Option C: Acrodont**. ---
