Among the following compounds ,which one is found is RNA?

Options

A.
B.
C.
D.

Explanation

To determine which compound is found in RNA from the given options, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Composition of RNA**:
RNA (Ribonucleic Acid) consists of four nitrogenous bases: adenine, guanine, cytosine, and uracil.

2. **Identify the Structures of the Bases**:
- **Adenine**: A purine base with a fused double-ring structure.
- **Guanine**: Another purine base, similar in structure to adenine.
- **Cytosine**: A pyrimidine base with a single six-membered ring.
- **Uracil**: A pyrimidine base similar to cytosine but lacks a methyl group.

3. **Analyze the Options**:
We need to compare the structures of the provided options with the structures of cytosine and uracil.

4. **Draw the Structures**:
- **Cytosine Structure**:
- It has an amine group (NH2) and a carbonyl group (C=O) in its structure.
- **Uracil Structure**:
- It has two carbonyl groups (C=O) and an amine group (NH).

5. **Compare Each Option**:
- **Option 1**: Check if it matches either cytosine or uracil. It does not match.
- **Option 2**: Check if it matches either cytosine or uracil. It does not match.
- **Option 3**: Check if it matches either cytosine or uracil. It does not match.
- **Option 4**: Check if it matches either cytosine or uracil. It matches uracil.

6. **Conclusion**:
After analyzing all options, the fourth option is confirmed to be uracil, which is found in RNA.

### Final Answer:
The compound found in RNA is **Option 4 (Uracil)**.
