Answer:
B
Explanation:
B is the answer BEcause if u pick A you think Ss tt and St st are seperate you are actually combining the four so when i solve the answer i got the answer of B because St and st have a possiblity that can become Sstt but there is another possibility that it can be Stst but i would rather go B instead of A. :) ☺☺
