The correct Answer is:
To solve the question "Shell is curved, tubular and open at both ends in," we will analyze the options provided and identify the correct answer step by step. ### Step 1: Understand the Characteristics of the Shell We are looking for a shell that is: - Curved - Tubular - Open at both ends ### Step 2: Analyze Each Option 1. **Dentalium**: This is known as a tooth shell or tusk shell. It is a marine mollusk with a shell that is indeed curved, tubular, and open at both ends. 2. **Chiton**: Chitons have a shell that is made up of eight overlapping plates. Their shells are not tubular and do not open at both ends. 3. **Neopilina**: Neopilina has a cap-like shell that is not tubular and does not fit the description of being open at both ends. 4. **Turbulina**: This is not a commonly recognized shell type that fits the description of being tubular and open at both ends. ### Step 3: Identify the Correct Answer Based on the analysis: - The only option that fits the description of having a shell that is curved, tubular, and open at both ends is **Dentalium**. ### Conclusion The correct answer to the question is **Dentalium**. ---
