Correct answer: C
First, determine the total bits per character frame by adding data, parity, start, and stop bits. The calculation is 7 data bits plus 1 parity bit, 1 start bit, and 1 stop bit, totaling 10 bits per character. Next, divide the transmission line speed of 19,200 bps by the frame size of 10 bits. This results in a maximum transmission rate of 1,920 characters per second.
