Which of the following is not a way that adaptation organisms?

a) increases ability to find/eat prey

b) increases ability to find/attract mates

c) makes them immune to all diseases

d) protects against difficult climate conditions

c) makes them immune to all diseases 

This is the choice you are looking for because is ISN'T a way that adaptation helps the organism survive life. If it is immune to all diseases, that organism would probably die because of all the diseases that it is immune to.
The other choices have adaptations that will help the organism survive. 

Hope I helped.
