Selected Answer: B
Agree with "B." You're removing sequence 30 and placing it in sequence 10 to then deny traffic from one PC to another. Sequence 20 was allowing traffic between them.

B seems indeed correct, you should always keep the existing permit and move the deny above in this use case. B does exactly do this.
