An African village was wiped out by a mystery infection. A neighboring village sent two men to investigate since they had not heard from their friends for a week.

Five computers in the office were found to be infected with a computer virus that allowed hackers to access their data. Five other computers were clean and therefore were not hacked.Explanation / Answer
As per kochs postulates the microorganisms are found in the people suffering from diseases but should not be found in healthy organisms. The microorganisms must be isolated and could be grown in pure cultures the culture microorganisms should cause disease when enter healthy organisms and the microorganisms must be reisolated from the diseased experimental host.
In this case the healthy people were attacked by the microbes which were inoculated from their dead friends.
In the case of last option the virus is found in infected systems and it was hacked but it was not found in healthy systems and they were not hacked so it is supporting kochsx postulate.
Regarding the first option there is no topic of antibodies in kochx postulate.
The second option also does not support kochs postulates as it is not mentioned about food poisoning in them.
