Explanation

A cold site requires the longest recovery time because it provides only the physical space and basic infrastructure (power, network connectivity) - no pre-installed hardware, software, or data exists, meaning everything must be procured, configured, and restored from scratch before operations can resume. A hot site (B) is wrong because it mirrors the production environment in real time with live systems and data, enabling recovery in hours or even minutes. A warm site (C) falls in between - hardware and software are pre-installed but data must still be restored, giving moderate recovery times (hours to days). A mobile backup site (D) is a portable trailer or van with pre-configured equipment that can be deployed quickly, so recovery is faster than a cold site.

Memory tip: Think of temperature as a proxy for readiness - the colder the site, the longer you wait to "warm it up" before it's usable. Cold = slow, Hot = fast.
