D Correct answer
Explanation

In manchester code, the bit duration is divided into the two halves. The voltage remains same at one level during first half and second half. It moves to the other level and the middle level to provide synchronization. It is like unipolar in which, the signal does not return zero at the middle of the bit and manchester is a combined feature of RZ and NRZ-L(polar). So, it is the correct option.
