Comprehensive and Detailed In-Depth Explanation:
A cold site is a disaster recovery location that provides only basic infrastructure (e.g., power, cooling, and space) but does not have pre-installed IT systems. Organizations must procure and install servers before recovery can begin.
Option A (Real-time data synchronization) applies to hot sites, which maintain fully operational backup systems.
Option B (Recovery time under one week) is more characteristic of warm or hot sites, as cold sites require longer setup times.
Option D (Defined recovery processes) applies to all disaster recovery plans and does not differentiate cold sites.
Since a cold site lacks pre-installed servers, Option C is the correct answer.
