Collision detection is regarded as the type of feature which should be turned on for half-duplex mode thereby making it the correct choice in this type of scenario.
What is Half-duplex mode?
This involves data transmission in both directions i.e they are bidirectional but doesn't usually happen at the same time while on the other hand full duplex mode is required all the time.
The collision detection is turned on as a result of the half duplex mode being more prone to collision as a result of the users attempting to transmit data at the same time while in full duplex mode data is permitted to be transmitted simultaneously. This therefore prevents the data from colliding with each other and not being properly propagated through their various channels.
