Explanation

Rightsizing is the process of analyzing and selecting the most appropriate EC2 instance types and sizes to match actual performance and capacity needs at the lowest possible cost - which is exactly what the company is doing. Auto Scaling (A) is incorrect because it automatically adjusts the number of instances based on demand, not the type or size of instances. Storage tiering (B) is unrelated, as it involves moving data between different storage classes (e.g., S3 Standard to S3 Glacier) based on access frequency. Instance scheduling (D) is incorrect because it refers to automatically starting and stopping instances at scheduled times to save costs, not selecting the right instance type.

Memory Tip: Think of "rightsizing" like buying the right-sized shirt - not too big (wasteful) and not too small (underperforming). If a question mentions matching instance types/sizes to requirements at minimum cost, that's always rightsizing.
