The total number of ones in the scattering matrix of an ideal circulator is: Correct Answer 3

Since the circulator is matched at all the ports, the diagonal elements are zero. As the circulator allows power flow in only one direction, only one of the elements in each row has a 1 in the matrix. With three rows, there are three ones.
