The correct Answer is:
To determine the lifespan of red blood cells (RBCs) in human blood, we can follow these steps: ### Step-by-Step Solution: 1. **Understand the Question**: We need to find out the lifespan of red blood cells in human blood from the given options: 30 days, 60 days, 120 days, or 15 hours. 2. **Identify the Full Form of RBC**: RBC stands for Red Blood Cells. They are crucial components of blood responsible for transporting oxygen throughout the body. 3. **Research the Lifespan of RBCs**: The lifespan of red blood cells is a well-documented fact in human physiology. 4. **Recall the Lifespan**: It is known that the average lifespan of RBCs in human blood is approximately 120 days. 5. **Compare with Other Blood Cells**: While considering RBCs, it's also useful to note that white blood cells (WBCs) have a shorter lifespan, typically ranging from 20 to 30 days, which highlights the longevity of RBCs compared to WBCs. 6. **Select the Correct Option**: Based on the information gathered, the correct answer to the question about the lifespan of RBCs in human blood is 120 days. ### Final Answer: The lifespan of RBCs in human blood is approximately **120 days**. ---
