Assertion (A): Digestion does not take place in large intestine.
Reason (R): Undigested food gets converted to faeces in large intestine.

Explanation

### Step-by-Step Solution:

1. **Understanding the Assertion (A)**: The assertion states that "Digestion does not take place in the large intestine." This is true because the large intestine primarily functions in the absorption of water and electrolytes, rather than the digestion of food.

2. **Understanding the Reason (R)**: The reason states that "Undigested food gets converted to faeces in the large intestine." This is also true. The large intestine processes the remaining undigested food, absorbing water and forming solid waste (faeces).

3. **Evaluating the Relationship**: Both the assertion and the reason are true. However, the reason explains why digestion does not occur in the large intestine. The large intestine's role is to handle undigested food, which is a consequence of the digestion process that has already taken place in the small intestine.
