The first option of the question is incomplete.
(b) killing of bacteria - in stomach as the pH of stomach is acidic (less than 2 pH)
(c) absorption of food - takes place in small intestine through villi and microvilli (the finger-like projections) which increases surface area for absorption.
(d) formation of faeces - takes place in last part of large intestine where large amount of water absorption takes place.
