Answer: D - Installing 10GbaseT will maintain the lowest cost for cabling in the datacenter.

Key Takeaway: 10GbaseT cabling is the standard for 10 Gigabit Ethernet over copper cabling. Specifically the 10GbaseT is much less expensive than 10GbaseSR, which refers to fiber that runs at the same speed. The “10base” standards refer to the 802.3 Ethernet standard set where the first part refers to the speed of the network media, the word refers to either baseband or broadband transmission, and the last part refers to a code that relates to either copper or fiber. For instance, 10BaseT is 10Mb copper (twisted pair) cable. Cat5e is not capable of reaching 10 Gigabit speeds and 10GbaseF is not an accurate term.
