Explanation Explanation for the correct answer: Option ( c ) is given as, it is maintained constantly within physiological limit. The blood pressure may fluctuate under different conditions, but the blood flow to the brain is maintained constantly because it is essential for the functioning of the brain. Hence, o ption ( c ) is correct. Explanation for the incorrect answer: Option (a ) is given as, varies with systemic arterial pressure. The brain needs a constant supply of oxygen as well as glucose for its proper functioning. Hence, the blood flow to the brain does not change with the variation in the systemic arterial pressure...
