Correct answer: B
NRZ encoding requires half the clock frequency of Manchester encoding for the same bit sequence. This is because Manchester encoding mandates a voltage transition in the middle of every bit period, effectively doubling the required signal frequency compared to the data rate. In contrast, NRZ encoding maintains a constant voltage level throughout each bit period without mandatory transitions.
