D. 0.2

Answer

To find the percentage of hemoglobin (Hb) in red blood cells (RBCs), we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Composition of RBCs**:
- Red blood cells primarily consist of hemoglobin, which is a protein responsible for transporting oxygen in the blood.

2. **Identify the Amount of Hemoglobin**:
- In a healthy individual, the amount of hemoglobin in RBCs is typically between 12 to 20 grams per deciliter of blood.

3. **Determine the Total Dry Content of RBCs**:
- The dry content of red blood cells is made up of various components, with proteins constituting about 96% of this dry content.

4. **Calculate the Percentage of Hemoglobin**:
- The percentage of hemoglobin in the total content of RBCs is approximately 34%. This means that if you consider the total content of the RBCs, hemoglobin makes up about 34% of it.

5. **Express the Percentage in Decimal Form**:
- To express this percentage as a decimal, we convert 34% to its decimal form, which is 0.34.

6. **Identify the Correct Option**:
- Based on the information provided, the correct answer to the question regarding the percentage of hemoglobin in RBCs is 0.34 (or 34%).

### Final Answer:
The percentage of hemoglobin in RBCs is **34%** or **0.34**.
