The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding the Question**: The question asks about the presence of a "hump" in frogs and toads while they are in a sitting posture. We need to analyze the anatomical features of both amphibians to answer this correctly. 2. **Defining "Hump"**: The term "hump" refers to a large round lump or elevation on the back. An example of this is the hump seen on the back of a camel. 3. **Analyzing Frogs**: Frogs are known to have a developed hump on their back. This feature is prominent and can be observed when they are in a sitting posture. 4. **Analyzing Toads**: In contrast, toads do not develop a hump. They have a more flattened body structure without the pronounced hump that frogs possess. 5. **Evaluating the Options**: - **Option A**: "Both frog and toad have a developed hump." - This is incorrect because only frogs have a hump. - **Option B**: "Frog has a hump which is absent in toad." - This is correct as frogs have a hump and toads do not. - **Option C**: "Toad has a hump which is absent in frog." - This is incorrect because toads do not have a hump. - **Option D**: "Both frog and toad lack a hump." - This is incorrect as frogs do have a hump. 6. **Conclusion**: Based on the analysis, the correct answer is **Option B**: "Frog has a hump which is absent in toad." ---
