Show answer & explanation
Correct answer: D
Concept
An acronym expansion is checked by mapping each letter to the initial letter of the corresponding word in its standard full form. A pair is mismatched when any supplied word differs from the accepted expansion, even when both words begin with the same letter.
Application
XML expands to Extensible Markup Language; the initials and the standard name align.
WWW expands to World Wide Web; the initials and the standard name align.
VLSI expands to Very Large Scale Integration; the initials and the standard name align.
SMS has the standard expansion Short Message Service. The supplied phrase Short Message Software replaces Service with Software.
Cross-check
Checking only the initials is insufficient because both Service and Software begin with S. Comparing the conventional full form therefore identifies SMS — Short Message Software as the incorrectly matched pair.
