💡 Solution & Explanation

For a zero-order reaction, the reaction rate is constant and independent of concentration. Because the rate remains unchanged, it takes proportionally less time to consume half of a smaller remaining amount. Consequently, successive half-lives decrease linearly as the initial concentration drops (t_1/2 ∝ [A]0). Therefore, correct answer is A.
