D Correct answer
Explanation

Variable-step ODE solvers dynamically adjust step size to maintain accuracy while optimizing efficiency. They take smaller steps during fast-changing dynamics and larger steps during smooth behavior, making them ideal for continuous systems. Fixed-step solvers either waste computation with unnecessarily small steps or lose accuracy with steps that are too large.
