Assertion: In animals, chemical digestion is necessary.
Reason: Mechanical digestion, typically, precedes chemical digestion, increasing the surface area for chemical digestion.
1. Both assertion and reason are true and the reason is the correct explanation of the assertion.
2. Both assertion and reason are true but the reason is not the correct explanation of the assertion.

4. Both assertion and reason are false.
Assertion: The secretion of bile by liver is important physiologically as it helps in the digestion and absorption of fats.
Reason: Bile contains bile pigments that help in first emulsification of fats and later absorption of fatty acids and glycerol through micelle formation.
