Consider a periodic counter in the count-down mode. The counter value at the time of events, e1 and e2 were c1, and c2 respectively. What can we say about e1, e2, c1, and c2?
A. C1 is more than C2 if e1 happens before e2.
B. C1 is less than C2 if e1 happens before e2.
C. C1 is can be either more than or less than C2 if e1 happens before e2.
