The lowest grade of utp that is rated for 100 mbps transmission is option A. CAT-5. CAT-5 was the first UTP standard ratified for 100 Mbps transmissions. Before that, CAT-3 was popular but only supported 10 Mbps. CAT-5e, CAT-6, and CAT-6a all support at least 1 Gbps and 100e after CAT-5. Hence, the correct answer is option A. CAT-5. Read below about CAT-5.
Category 5 cable (Cat 5 or Cat5) is a twisted pair cable for carrying signals. This type of cable is used in structured cabling for computer networks such as Ethernet. The cable standard provides performance of up to 100 MHz and is suitable for 10BASE-T, 100BASE-TX (Fast Ethernet), and 1000BASE-T (Gigabit Ethernet).
