I would say A

Smoking, small bowel, fistulas and strictures and perianal region involvement are associated with CROHN's disease.

good job!
This is truly UC


I chose E blindly (perianal is Crohn's of course...), wordings got me here...

Smoking is a protective factor against ALzheimers and UC...

a. bleeding from rectum during b.m. is common

I think smoking protects against ulcerative colitis.
