Dear, Fats are digested in small intestine, starch and carbohydrates in mouth via saliva. And Pancreas secretes insulin. Its gall bladder that secretes bile in small intestine.

Thanks for the corrections. After almost two years I attempted biology MCQs. And how stupid, this insulin production by pancreas complete went out of my mind, hehehe.

And about largest organ. Yep! It is skin but in case where it's not given I think liver is the only option to go with. Since, it's the largest glandular organ. I already made it clear in this thread:
