_____dominates the LSI field, and _____ is used extensively where lowest power consumption is necessary. A. NMOS, PMOS B. PMOS, CMOS C. NMOS, CMOS D. MOSFET, PMOS E. None of the above

The correct answer is C. NMOS dominates the LSI field, and CMOS is used extensively where lowest power consumption is necessary.

NMOS (n-channel metal-oxide-semiconductor) and PMOS (p-channel metal-oxide-semiconductor) are both types of MOSFETs (metal-oxide-semiconductor field-effect transistors). MOSFETs are the most common type of transistor used in integrated circuits (ICs).

NMOS transistors are typically used in LSI (large-scale integration) circuits, which are ICs with millions or billions of transistors. CMOS transistors are typically used in VLSI (very-large-scale integration) circuits, which are ICs

CMOS transistors are more power-efficient than NMOS transistors. This is because CMOS transistors use complementary pairs of NMOS and PMOS transistors, which cancel each other out when they are not

As a result, CMOS is used extensively in applications where low power consumption is important, such as mobile devices and battery-powered systems.
