Answer: A
The demarcation or demarc is the juncture at which the CPE
ends and the
local loop portion of the service begins. The CO (Central
Office) is the
nearest point of presence for the provider's WAN service.
The local loop
or "last-mile" is the cabling that extends from the demarc
into the WAN
service provider's central office.
