I have been asked this question by my college director while I was bunking the class.

I'd like to ask this question from Ring Counter topic in division Registers of Digital Circuits

Answer 1

The correct option is (d) A single 1, the rest 0

The best explanation: A ring shift counter is a counter in which the output of one FF connected to the input of the adjacent FF. In preset condition, all of the bits are 0 except first one.
