A. B. C. D. E.

Answer: A and E are correct statements.

Explanation: 1000BASE-T is an Ethernet standard that defines the transmission of data over unshielded twisted pair (UTP) cables at a rate of 1 gigabit per second (Gbps). Here are the explanations for each statement:

A. It uses four wire pairs: 1000BASE-T uses four wire pairs, which means it requires eight wires in total. Each pair is used to transmit and receive data, which means that four pairs are used in total for full-duplex communication.

B. It is most appropriate for installations up to 1000 feet in length: This statement is not correct. The maximum distance for 1000BASE-T UTP cable is 100 meters (328 feet). If the cable length is longer than this, it may result in signal degradation or loss of data.

C. It is most appropriate for installations up to 1000 meters in length: This statement is not correct. As mentioned above, the maximum distance for 1000BASE-T UTP cable is 100 meters (328 feet), so it is not appropriate for installations up to 1000 meters.

D. Both ends of the cable can transmit and receive simultaneously: This statement is not correct. 1000BASE-T uses a twisted pair signaling scheme called "adaptive equalization" to mitigate the effects of signal attenuation and crosstalk, which enables simultaneous bidirectional communication over a single pair of wires, but not both ends of the cable.

E. It uses four wires: This statement is correct, but more specifically, it uses eight wires in total, with four pairs of wires.

In summary, the correct statements are A and E.
