Which of the following types of connectors can use a maximum of 8 strands of wires?
The correct answer is C. RJ-45. RJ-45 is the only connector listed that accommodates up to 8 conductors (4 twisted pairs), making it the standard for Ethernet network cabling.

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.
RJ-11 connectors have only 6 positions and typically use 2 or 4 conductors, used primarily for telephone connections.
RS-232 is a serial communication standard that uses DB-9 or DB-25 connectors, not an 8-conductor RJ-style connector.
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.
BNC is a coaxial connector with a single center conductor and shield, used in legacy 10BASE2 Ethernet and RF applications.
