On a multi-line telephone, the line in use will be indicated by what?

• A. A blinking red light
• B. An audible beep
• C. A steady light
• D. A flashing icon

Answer: (C)

When a line is actively being used on a multi-line phone, the indicator for that line stays on steadily. That continuous light clearly shows which line is in use, helping you stay oriented during a busy call setup. A blinking light usually signals something else, like an incoming call or a line that's ringing, not an already active conversation. An audible beep is simply a sound cue, not a persistent visual status for the line in use, and a flashing icon isn’t a standard way to indicate active use.
