- A.
10,000 bytes
- B.
12,000 bytes
- C.
15,000 bytes
- D.
27,000 bytes

Show answer & explanation
Correct answer: B
Answer: 12,000 bytes
Assumption: 8 data bits per character (common default). If the number of data bits differs, recalculate accordingly.
Determine bits per asynchronous frame: 1 start bit + 8 data bits + 1 parity bit + 2 stop bits = 12 bits per character.
Compute characters (bytes) per second: 9600 bits/s ÷ 12 bits/character = 800 characters/s.
Compute total bytes in 15 seconds: 800 characters/s × 15 s = 12,000 bytes.
Therefore the correct answer is 12,000 bytes.
