Have a doubt in ring counter

[ashwini jayaraman]

If an 8-bit ring counter has an initial state 10111110, what is the state after the fourth clock pulse?

A. 11101011 B. 00010111
C. 11110000 D. 00000000

When I did this, I got an answer A.

What i did is right?? can anyone explain me?

1. For the 1st clk pulse, it would be, 01011111
2. For the 2nd clk pulse, it would be, 10101111
3. For the 3rd clk pulse, it would be, 11010111
4. For the 4rth clk pulse, it would be, 11101011

Is my method right?
