A. Reserved instances

B. On-demand instances

C. Spot instances

D. Regular instances

Answer - A.

When you have instances that will be used continuously and throughout the year, the best option is to buy reserved instances.

By buying reserved instances, you are actually allocated an instance for the entire year or the duration you specify with a reduced cost.
