The correct Answer is:
To solve the given question, we will analyze both the assertion and the reason step by step. ### Step 1: Understand the Assertion The assertion states that an increase in blood flow to the atria of the heart can cause the release of ANF (Atrial Natriuretic Factor). - **True or False?**: This statement is **True**. Increased blood flow leads to increased pressure in the atria, which stimulates the release of ANF. ### Step 2: Understand the Reason The reason states that ANF can cause vasodilation and decrease blood pressure. - **True or False?**: This statement is also **True**. ANF promotes vasodilation, which helps to lower blood pressure. ### Step 3: Determine the Relationship Now we need to determine if the reason is a correct explanation of the assertion. - The assertion explains that increased blood flow leads to ANF release due to increased atrial pressure. The reason explains the effects of ANF, including vasodilation and decreased blood pressure. - While both statements are true, the reason does not directly explain why ANF is released; it explains what ANF does after it is released. ### Conclusion Since both the assertion and reason are true, but the reason does not correctly explain the assertion, the correct answer is: **(b) If both Assertion & Reason are True but Reason is not a correct explanation of the Assertion.** ---
