$\underline{{\textbf {Answer: A}}}\implies$ DMA Based I/O Transfer

$\underline{{\textbf {Explanation: }}}\implies$

DMA(Direct memory access) is used for transferring bulk data from Main Memory with the highest throughput as the CPU is unable to access the hard disk directly.
DMA helps in the effective utilization of the CPU’s time.

Another method used for data transfer in a similar fashion is programmed Input/Output but this method is quite slow.
