Answer options:

Backup and Restore
B.
Pilot Light
C.
Warm standby
D.

E.
AWS Storage Gateway Volume Gateway
How to approach this question
Understand the DR spectrum. RTO of 5 minutes requires infrastructure to already be running (Warm Standby or Active-Active).
Full Answer
To achieve an RTO of 5 minutes, you cannot wait to provision resources. Warm standby keeps a scaled-down version running, and Multi-site active-active keeps full capacity running in multiple regions.
Common mistakes
Selecting Pilot Light, which usually has an RTO of tens of minutes because compute instances must be started.
