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

Correct option is A

CMOS-Consistent Metal-Oxide Semiconductor this is incorrect. The correct expansion of CMOS is Complementary Metal-Oxide Semiconductor.
Complementary Metal-Oxide Semiconductor (CMOS) is a type of transistor technology used in integrated circuits (ICs), also known as microchips. It is the most widely used technology for building chips due to its advantages in power consumption, speed, and density.
 CMOS uses complementary pairs of p-type and n-type transistors to create logic circuits.
 P-type transistors conduct electricity when a positive voltage is applied, while n-type transistors conduct when a negative voltage is applied.
 This complementary design allows CMOS circuits to consume very little power when idle, as only one type of transistor conducts at any given time.
