B
Correct answer
Explanation
Computer monitors are typically connected to the system unit via a cable (such as VGA, DVI, HDMI, or DisplayPort cables). While 'wire' is physically similar, 'cable' is the correct terminology for monitor connections. A bus is internal to the computer, and line driver is an electronic component, not a connection method.
B
Correct answer
