A. Parity bit
B. Status bit
C. Zero bit
D. Start bit
Check Answer
The correct answer is D) Start bit.
In asynchronous communication, data is transmitted in a series of bits, with each byte of data being framed by a start bit and a stop bit. The start bit is always a value of 0 and indicates the beginning of a new byte of data. The stop bit is always a value of 1 and indicates the end of a byte of data.
Option A (Parity bit) is an additional bit that may be added to a byte of data to detect errors in transmission. It is not used to indicate the start of data transmission.
Option B (Status bit) is a bit used to indicate the status of a device or system, and is not related to data transmission.
Option C (Zero bit) is not used as a start bit in asynchronous communication.
Therefore, the correct answer is D) Start bit.
