Involuntary striated muscles, also known as smooth muscles, do not experience fatigue in the same way as skeletal muscles. Smooth muscles have different properties and mechanisms for contraction and energy production compared to skeletal muscles. Fatigue in skeletal muscles is mainly attributed to the depletion of ATP and the accumulation of metabolic byproducts, whereas smooth muscles are more resistant to fatigue due to their slower contraction and reliance on aerobic metabolism. Therefore, the reason provided is incorrect, and the assertion itself is false.Hence, the correct answer is option 4
