QUESTION 1 Why is it necessary to perform bit stuffing on a data link that uses framing? Because there may not be sufficient room to send all the control information necessary to interpret the frame so additional bits "containing this information must be added. B. Because additional bits are required to allow error detection and/or correction to take place. Because a bit pattern in the data payload could emulate the frame delimeter, causing the receiver to believe it had received a frame OC. shorter than what was actually sent. O D. Because additional bits added to the frame reduce the chances of errors in the frame
