Answer 1

The correct option is B

i). $\Rightarrow$ d., ii). $\Rightarrow$ a., iii). $\Rightarrow$ b., iv). $\Rightarrow$ c

The correct matching pairs are :
Intracellular digestion takes place in amoeba. Amoeba is an unicellular organism and it ingests food through phagocytosis, and stores it inside the body in a vacuole. The digestion takes place inside the vacuole, within the body of the organism and therefore it shows intracellular digestion.
Digestion in humans occur inside the alimentary canal that is a hollow digestive tract that enables ingestion, digestion and absorption of food. It does not occur inside cells and therefore is extracellular digestion.
Breaking food down into smaller particles, such that you increase the surface area of the food materials occurs in the oral cavity of many animals through a process called mastication or chewing.
Biochemical disgestion is the breakdown of small food particles with the help of enzymes, therefore it is also called enzymatic digestion.
