The correct Answer is:
To solve the question "Eggs are covered with a tough, leathery coat in case of", we need to analyze the options provided: sharks, bony fishes, lizards, and eurocordates. ### Step-by-Step Solution: 1. **Understanding Egg Development**: - Eggs can develop either inside the female body (viviparous) or outside in a protective shell (oviparous). Oviparous organisms lay eggs that need protection from environmental conditions. 2. **Analyzing the Options**: - **Sharks**: Sharks can be either oviparous or viviparous. However, since they are aquatic, their eggs do not require a tough leathery coat for protection. - **Bony Fishes**: Similar to sharks, most bony fishes are oviparous and lay their eggs in water. They do not need a tough leathery coat as their eggs are also protected by the aquatic environment. - **Lizards**: Lizards are terrestrial reptiles that lay eggs on land. Their eggs need protection from the harsh environmental conditions, which is why they have a tough, leathery coat. These eggs are referred to as cleidoic eggs. - **Eurocordates**: Eurocordates are primarily aquatic organisms and, like sharks and bony fishes, their eggs do not have a tough leathery coat. 3. **Conclusion**: - The only option where the eggs are covered with a tough, leathery coat is **lizards**. Therefore, the correct answer is **lizards**. ### Final Answer: **Lizards**
