Line break for URL clash with hyperref

Question

I want to put a line break for the urls as it exceeds the page margin. I've refereed couple of posts on StackExhange but still it's not successful. The error for the following code says !LaTeX Error: Option clash for package hyperref.

Any help in resolving this is much appreciated.
