Why each option
A standard CATV cable system is defined by three functional elements - headend, distribution system, and subscriber drop - while a television is a consumer endpoint device that is not part of the cable plant itself.
The headend is a core element of a cable system where signals are received, processed, and combined for transmission to subscribers.
The distribution system - including trunk and feeder cables, amplifiers, and passive devices - is the infrastructure that transports signals from the headend to subscriber areas and is a defined element of the cable plant.
The subscriber drop is the final cable segment connecting the distribution network to an individual subscriber's location and is a recognized functional element of the cable system.
A television is a terminal consumer device that receives and displays the signal delivered by the cable system; it is not considered an element of the cable distribution system, which is formally defined by the signal origination point (headend), the signal transport infrastructure (distribution system), and the final connection to the subscriber premises (subscriber drop).
