Out of a total of N students at a school, the number of students who have seen a new television program increases at a rate proportional to the product of the number of students who have seen the program and the number of students who have not seen the program. If S denotes the number of students who have seen the program at time t, which of the following differential equations could be used to model this situation, where k is a positive constant?a. ds/dt = KSb. ds/dt = kt(N-t)c. ds/st = KS(N-S)d. ds/dt = KS(S-N)
