Which solution will meet this requirement?

Accepted Answer

**Answer A: Compute Savings Plan with a 3-year commitment** is correct for several key reasons:

   - Change instance families (e.g., from m5 to m6i)
   - Change instance sizes
   - Change regions

   Compute Savings Plans accommodate ALL of these changes.
