The correct Answer is:
To solve the question, we need to analyze both the Assertion and the Reason provided: ### Step 1: Understand the Assertion The assertion states that "On repeated application of stimuli, involuntary striated muscles undergo fatigue." - Involuntary striated muscles (like cardiac muscles) can indeed experience fatigue, but this typically occurs under conditions of extreme or prolonged activity. However, they are generally more resistant to fatigue than voluntary muscles. ### Step 2: Understand the Reason The reason states that "This is due to non-availability of ATP molecules." - ATP (adenosine triphosphate) is essential for muscle contraction. While a lack of ATP can lead to muscle fatigue, it is not the only factor. Oxygen availability also plays a crucial role in ATP production through aerobic respiration. ### Step 3: Evaluate the Truth of Each Statement - **Assertion**: The assertion is misleading. While involuntary striated muscles can experience fatigue, they do not do so simply from repeated stimuli in a general sense. Therefore, the assertion is **false**. - **Reason**: The reason is also misleading. While ATP availability is important, fatigue can also occur due to other factors such as oxygen availability. Thus, the reason is also **false**. ### Conclusion Since both the assertion and the reason are false, the correct answer is: **(d) If both Assertion and Reason are false.** ---
