To ensure that the given output is printed we need to take values as S=1 and T=0.
To ensure that it prints only (0011)* only, we need to take W: P(S), X:V(T) not X:V(S) as it leads to printing 0000……
Also, Y:P(T) and Z:V(S) such that 00 can be printed only after 11 is printed.
Therefore, answer is option b.
