Correct Answer - Option 1 : twisted-pair wire
The slowest transmission speed are those of Twisted pair wire
The main purpose of twisted wires is to reduce crosstalk and electromagnetic induction. While twisted-pair cable is used by older telephone networks and is the least expensive type of local-area network (LAN) cable, most networks contain some twisted-pair cabling at some point along the network.
Crosstalk between wires is cancelled when an interfering signal is applied equally to both sides of a twisted-pair wire. Twisted-pair wiring can also be wrapped with a shielding conductor sheath, which acts as an electrostatic shield.
