B Correct answer
Explanation

Molex connectors are the standard 4-pin power connectors used to supply electricity to internal optical drives like CD-ROM and DVD drives, as well as hard drives. They provide +5V and +12V power rails. DB-15 connects older game ports or monitors, PS/2 is for keyboards and mice, and RJ11 is for telephone lines - none of these power disc drives.
