Correct answer: B
Acronym-matching questions test whether the expansion given for an abbreviation matches its standard, universally accepted full form. A pair is "incorrectly matched" when the stated expansion diverges from that standard definition, even if it sounds plausible.
Checking each pair against its standard, authoritative expansion:
Acronym | Given expansion | Standard expansion | Match? |
|---|---|---|---|
FTP | File Transfer Protocol | File Transfer Protocol | Matches |
SMTP | Simple Mail Technology Protocol | Simple Mail Transfer Protocol | Does not match |
UDP | User Datagram Protocol | User Datagram Protocol | Matches |
ROM | Read Only Memory | Read Only Memory | Matches |
Only the SMTP row shows a mismatch: the standard, RFC 5321-defined expansion is "Simple Mail Transfer Protocol", not "Simple Mail Technology Protocol". Every other pair matches its standard expansion exactly, so "SMTP - Simple Mail Technology Protocol" is the incorrectly matched pair and the correct answer to this question.
