The statement which is correct is
<em>The evolutionary fitness associated with the heritable trait of DDT resistance changed once DDT use became widespread.</em>
Explanation:
In the 1930's, the usage if insecticides was minimal. Hence, the genes for DDT resistance were absent or silent in the fruit flies at that time.
In the 1960's, the DDT resistant forms of fruit fly began occurring at this rate because they were better adapted to survive. According to Darwin, the species which are better able to adapt to the environment survive and are able to reproduce. Hence, with the passage of time the resistant forms of fruit fly will keep reproducing and increase in number.

There are many different believes when it comes to this topic. Some people believe that there is no god and evolution did happen and then you have the opposite where some people believe evolution didn't happen and there is a god. But then there are some people I have come across who believe in both. Now there is a lot of evidence that can point to evolution actually happening but there is still many unanswered questions and gaps. In my personal opinion I think it is still too early to explain wether evolution happened, just because having spent studying this topic I realized there was a very important chunk of information missing. You may have heard that scientist have tried to connect apes with humans but they haven't quite fit in that puzzle piece. Personally I'm a christian but I am still open-minded to the idea of evolution. Hope this helps(;
