D Correct answer
Explanation

SCSI (Small Computer System Interface) provides the fastest data transfer among the listed options because it supports high-speed data rates, multiple devices on a single channel, and independent data paths. Parallel and Serial interfaces are significantly slower, while IDE (Integrated Drive Electronics) is an older standard with lower performance. Direct CPU Bus is not a standard interface type for peripheral data transfer.
