Solution

The results support the hypothesis 2 that is the warning of bat about the moth\'s toxic chemical defense. This is because in the species A the results initially showed the capture of the moths but slowly the capture decreases which shows the effect of the warning of the moths for the toxic chemicals.

The reason behind the researchers choosing the naive bats is because the bats which have hunted moths earlier knows the pattern and will not give desired results. as the bats are naive the pattern of hunting moths will be new and will give perfect results regarding both the hypothesis.
