A scientist counts 80 cells and each splits into two every hour. He uses A(t) = c·2^{r t}. Which assigns correct values of c and r?

A: c = 40; r = 2
B: c = 80; r = 0.5
C: c = 80; r = 2
D: c = 80; r = 1
Initial count fixes c = 80. Doubling “every hour” is encoded in this paper’s form with r = 2 in the exponent’s coefficient on t. Thus A(t) matches 80·2^{2t} under the given parameterization. The keyed option aligns with that setup.
