Which of the following pairs of an acronym and its expanded form is incorrectly matched?

CMOS actually stands for Complementary Metal Oxide Semiconductor, so the expansion given as Consistent is the wrong one.

DRAM correctly expands to Dynamic Random Access Memory, the main volatile memory needing constant refresh.

MICR correctly expands to Magnetic Ink Character Reader, used to read cheque numbers printed in magnetic ink.

VLSI correctly expands to Very Large Scale Integration, packing thousands of transistors on one chip.

The word Complementary refers to the paired n-type and p-type transistors that make CMOS low in power use.
