D Correct answer
Explanation

FETs (Field Effect Transistors) in linear ICs serve two key purposes: they provide very large resistances in small chip area and significantly increase input impedance due to their high gate resistance. This makes them ideal for input stages and for creating large-value resistors that would be impractical with standard resistive components.
