$J _{a} = JQ_{a}' + K'Q_{a} = Q_{a}' + Q_{b}$
Similarly,
$J _{b} = JQ_{b}' + K'Q_{b} = Q_{c}.Q_{b}'$
and,
$J _{c} = JQ_{c}' + K'Q_{c} = Q_{c}' + Q_{a}$

*PS = Present State
Hence, from the table above, we can infer that the state changes are $S_{5}\rightarrow$$S_{3}\rightarrow$ $S_{4}\rightarrow $$S_{1}\rightarrow$ $S_{6}\rightarrow $$S_{5}$.
So, the answer is A)
