RJ45 stands for which of the following?

Explanation:
RJ stands for Registered Jack, and the number identifies the specific jack type. RJ-45 is the standard Ethernet connector, a registered jack with the designation 45. The word “Function” isn’t part of the official name, so that option isn’t the correct expansion. The phrase “Registered Jack” alone is related, but the full, accurate designation is Registered Jack 45. The other choices are unrelated (for example, Read-only Memory is a different tech term).
