Hi,
Sounds like you a question from an exam.
That particular frequecy can give 9600 baud rate which will give theoritically 0% error.
External crystak oscillators are supposed to be more reliable. In most of the designs the internal oscillator is used as a back up only whenever the external oscillator fails.
