C) look for a male connector with 9 pins.

Explanation:

Serial ports are male ports, identified as OIO, and they have a 9-pin or a 25-pin connector.

They are still used by some relatively old equipment like point of sales systems and some industrial systems. But they are also used as control consoles for carrying on diagnostics on large server computers.

Serial ports have been replaced by USB ports which are much faster as smaller.
