A serial transmission Ti uses 8 information bits, 2 start bits, 1 stop bit and 1 parity bit for each character. A synchronous transmission T2 uses 3 eight bit sync characters followed by 30 eight bit information characters. If the bit rate is 1200 bits/second in both cases, what are the transfer rates of Ti and T2?

• A. 100 characters/sec, 153 characters/sec
• B. 80 characters/sec, 136 characters/sec
• C. 100 characters/sec, 136 characters/sec
• D. 80 characters/sec, 153 characters/sec
