The correct answer emphasizes the importance of sufficient floor height in data center design, which is critical for several reasons. A floor height of 4 meters is ideal because it allows for the installation of raised flooring systems, which are essential for efficient cabling, cooling systems, and air circulation. Such height also provides flexibility for large cooling units and other equipment that need to be above the operational floor.

In this context, ensuring that the data center design allows for proper airflow, cooling, and equipment clearance is vital to maintaining optimal operating conditions. While the lack of facilities in this particular choice may raise concerns, the priority here is on having an adequate vertical space to accommodate the operational needs of the data center. This ensures that the facilities can be properly managed and that critical systems, including cooling and power management, can function effectively without obstruction.

In contrast, other options lack either adequate height, layout, or infrastructure considerations, which would compromise the data center's operational efficiency and resilience.
