B Correct answer
Explanation

Parallel ports transfer data simultaneously across multiple lines (typically 8 bits for data), achieving speeds of 2-3 MB/s with IEEE 1284 standard. Serial ports transmit one bit at a time and are much slower (115-460 kb/s for RS-232). PS/2 ports are for keyboards/mouse and are slower than parallel. Among the given options, Parallel is the fastest port type.
