The correct Answer is:
To solve the question, we will evaluate the assertion and the reason separately, and then determine their relationship. ### Step 1: Evaluate the Assertion The assertion states that the total content of iron in an adult body is 3.5 grams and that iron deficiency leads to anemia. - **Analysis**: - The average amount of iron in an adult human body is indeed approximately 3.5 grams. This is a well-established fact in human biology. - Iron is essential for the production of hemoglobin in red blood cells. A deficiency in iron can lead to a decrease in hemoglobin levels, resulting in anemia. - **Conclusion**: The assertion is **True**. ### Step 2: Evaluate the Reason The reason states that iron (Fe²⁺) combines with the pigment porphyrin to form heme. - **Analysis**: - It is correct that iron combines with porphyrin to form heme, which is a critical component of hemoglobin. - However, the reason does not explain how iron deficiency leads to anemia. It only describes a part of the process (the formation of heme) without linking it back to the production of hemoglobin or the consequent effect on red blood cells. - **Conclusion**: The reason is **True**, but it does not adequately explain the assertion. ### Step 3: Determine the Relationship Now we need to determine if the reason is a correct explanation of the assertion. - Since both the assertion and the reason are true, but the reason does not explain the assertion, we conclude that the assertion is true and the reason is true but not a correct explanation of the assertion. ### Final Answer - The assertion is **True**. - The reason is **True**, but it is **not a correct explanation** of the assertion.
