A Correct answer
Explanation

SCSI defaults to asynchronous data transfer mode, where each byte/word transfer requires handshaking signals (REQ/ACK) before the next can begin. Synchronous transfer is an optional negotiated mode that allows multiple data transfers per handshake cycle, improving throughput. 'Semi-synchronous' is not a standard SCSI transfer mode. The default is asynchronous for maximum compatibility.
