If stimulating current pulse 9 (not shown) was both stronger and longer than stimulating current pulse 8, then

A) the train of action potentials would continue for the length of the stimulating current.
B) action potentials would increase in amplitude.
C) action potentials would first increase in frequency and then decrease.
D) the line at stimulus 9 would look exactly same as the line at stimulus 8.
