Solve the problem.The spread of a cold virus can be modeled using logistic equations. The key assumption is that at any given time, a fraction y of the population, where 0 ? y ? 1, has the virus, while the remaining fraction src="https://sciemce.com/media/4/ppg__wesa0610191635__f1q17g3.jpg" alt="" style="vertical-align: -4.0px;" /> and solve the initial value problem where the number of people who initially have the cold virus is 
does not. Furthermore, the cold virus spreads by interactions between those who have it and those who do not. The number of such interactions is proportional to y(1 - y). Therefore, the equation that describes the spread of the virus is 
where k is a positive real number. Assume 
A. y = 
B. y = 
C. y = 
D. y =
