I need help I’m behind

The answer to this question is given below in the explanation section.

Explanation:

You use a really long cable to connect the desktop computer in your bedroom to the router on the other side of your house. Which of these may be a problem?

The correct answer to this question is  Attenuation.

Attenuation is the loss of signal strength in networking cables or connections. This may occur when the cable is spread over a long distance.   Attenuation is typically measured in  (dB) decibels or voltage and can occur due to a variety of factors. Attenuation occurs in the cable when there is a reduction in power of the light signal as it is transmitted.

Other options are not correct because IP/MAC confusion will not occur due to long-distance cable. Lack of input device may not create the problem and adaptation also.

i do not get the question.
