Option A
Unshielded twisted-pair cable capable with a specification of 100 MHz/100 Mbps is also called Category 5
Step-by-step explanation:
Category 5 is the network cable that is extensively used for 100Base-T channels as it renders enforcement to provide data at 100 Mbps and imperceptibly added Ethernet. The Cat 5 cable outmoded the Cat 3 version and for manifold years it grew the pattern for Ethernet cabling. Cat 5 cable practices twisted pairs to override innate crosstalk.
Category 5 cable is customarily 4 combo high-performance cable that consists of twisted couple conductors, employed essentially for data transmission. Unshielded Twisted Pair organization offers the cable extremely cost-effective for data channels.
