Why each option

RJ-45 is the only connector listed that accommodates up to 8 conductors (4 twisted pairs), making it the standard for Ethernet network cabling.

ARJ-11

RJ-11 connectors have only 6 positions and typically use 2 or 4 conductors, used primarily for telephone connections.

BRS-232

RS-232 is a serial communication standard that uses DB-9 or DB-25 connectors, not an 8-conductor RJ-style connector.

CRJ-45Correct

RJ-45 connectors have 8 positions and 8 conductors, supporting all 4 pairs of wire in a standard Ethernet cable - this 8-strand capacity is a defining physical characteristic of the RJ-45 standard.

DBNC

BNC is a coaxial connector with a single center conductor and shield, used in legacy 10BASE2 Ethernet and RF applications.
