• B)if more individuals in the population become infected,fewer people are able to spread the disease,and the vulnerable members of the population are less likely to come in contact with contagious individuals.
• C)if more individuals in the population become infected,more people are able to spread the disease,and the vulnerable members of the population are less likely to come in contact with contagious individuals.
