Correct Answer: A
Explanation:
Based on the rules, Statement B cannot be considered, because Hop must
be performed before Top, which is reversed in Statement B and thus contradicts the rules, rejecting it as
a possible answer. Similarly, Statement C also cannot be considered, because Bop must follow after Cop
according to the rules, which is contradicted here, thus eliminating Statement C from further
consideration. Finally, Statement D must be rejected because Sop, the first entry in this option, cannot
precede Cop according to the initial conditions; since it contradicts that rule, it is an invalid statement
and must be rejected. Only Statement A follows the rules as outlined in the question, which makes A the
correct answer.
