Show answer & explanation
Correct answer: C
Concept
An acronym is checked against the recognized words represented by its letters; replacing a word with a near-synonym changes the official expansion.
For standard technology terms, each letter must align with the accepted full name.
Application
The recognized expansions are MIDI—Musical Instrument Digital Interface, LED—Light Emitting Diode, MPEG—Moving Picture Experts Group, and PDF—Portable Document Format.
Contrast
MIDI uses Interface as its final word.
LED denotes a diode that emits light.
MPEG uses Moving Picture, not Motion Pictures, in the group name.
PDF uses Portable Document Format.
Result
Therefore, MPEG — Motion Pictures Experts Group is the incorrectly matched pair.
