For which values of a, b, and c will the population of the bacterial colony described by the equation B' (t) = eat-b - ct be the greatest at t = 3? The initial population of the bacterial colony is B(0) = 2, where units are in thousands of cells. O a) a = 0.26, b = 0.16, c = 0.38 O b) a = 0.79, b = 0.51, c = 0.55 O c) a = 0.76, b = 0.63, c = 0.29 O d) a = 0.39, b = 0.15, c = 0.42
