Show answer & explanation
Correct answer: C
The line speed is 19.2 kbps, which equals 19,200 bits per second. Each character frame consists of 7 data bits plus 1 parity bit, 1 start bit, and 1 stop bit, totaling 10 bits per character. Dividing the total bandwidth by the frame size yields 19,200 divided by 10, which equals exactly 1,920 characters per second.
