Explanation:
In trial A, people have no immunity so there are more chances of infection and in trial C, only 50% of people have immunity so chances of infection are less, so infection will spread faster in trial A than trial C.
If compared, trial C will have less infected people than trial A because people in trial A has no immunity and people in trial C have 50% of immunity, so only fewer people will get infected even after six point of contact.
As percentage of immune people (trial C) is 50, so there are equal chances of immunity and non-immunity. there are three reasons of infection that include source, susceptible person and transmission. source and susceptible person can be the reason of infection in some non-immune people but the transmission reason can vary. s<em>o, there is probability that three nonimmune people lie under transmission reason and are not coming in contact with infected people, medical equipment or environment, that causes infection and those three people are not getting infected.</em>
<em>Hence, the correct options are 1, 3 and 4.</em>

You're talking about sexual reproduction and asexual reproduction, right?
Well, when there are favourable conditions they use the asexual reproduction because they want to produce as may individuals as possible with the lowest energy use possible.
When the conditions are no longer favourable, they use sexual reproductions, because the egg is more resistant to the unfavourable conditions and is more likely to thrive.
