Carbohydrates are not absorbed by the stomach, but rather by the small intestine. Once absorbed, they are delivered to the liver through the portal vein. Fatty acids are indeed absorbed by the intestinal mucosa and then transported through the lymphatic system. Proteins are digested into amino acids, which are then absorbed by the intestinal mucosa and also delivered to the liver through the portal vein. Therefore, statements II and III are correct, but statement I is not. Choice C, which includes II and III, is the best answer.
