Answer:
C. Resistor
Step-by-step explanation:
A discrete component can be defined as any electronic component that are built as an individual or single unit.
Basically, a discrete component comprises of a single circuitry element, either an active element such as a vacuum tube, transistor etc or a passive element such as a resistor, diode, capacitor, inductor etc.
Hence, a discrete component is different from an integrated circuit (IC) or hybrid circuits because it is typically constructed or built with a single circuit element while integrated or hybrid circuits are constructed as a multiple unit.
Additionally, most discrete component are mainly semiconductors and as such consume large amounts of current.
