Show answer & explanation
Correct answer: C
RTL (Resistor-Transistor Logic) is a saturated bipolar logic family because its transistors operate in saturation during switching. ECL (Emitter-Coupled Logic) avoids saturation to achieve high-speed switching, so it is classified as a non-saturated bipolar logic family. Therefore, both statements I and II are correct.
