All carbohydrates and lipids have similarity in possessing -

Options

A. C, H, O
B. N, S, Protein
C. Carboxylic and amino group
D. Carboxylic and hydroxyl group

Answer

To answer the question regarding the similarity between carbohydrates and lipids, we can break down the solution into the following steps:

### Step-by-Step Solution:

1. **Identify the Compounds**:
- Carbohydrates and lipids are both organic compounds. They are essential biomolecules found in living organisms.

2. **Common Elements**:
- Both carbohydrates and lipids are composed of three primary elements: carbon (C), hydrogen (H), and oxygen (O). This is a significant similarity between the two.

3. **Source of Energy**:
- Both carbohydrates and lipids serve as energy sources for the body. Carbohydrates are typically the primary energy source, while lipids provide a secondary source of energy.

4. **Examine Other Options**:
- The other options provided (nitrogen, sulfur, carboxylic groups, and amino groups) do not apply as similarities between carbohydrates and lipids.
- Carbohydrates do not contain nitrogen or sulfur as primary components, and the functional groups mentioned (carboxylic and amino) are not common to both.

5. **Conclusion**:
- Based on the analysis, the correct answer to the question is that carbohydrates and lipids both possess carbon, hydrogen, and oxygen.

### Final Answer:
The similarity between carbohydrates and lipids is that both are composed of carbon, hydrogen, and oxygen.
