C. Chyle
D. Fat body

Answer

To answer the question "Food bolus after passing through alkaline medium in the alimentary canal is called as?", we can break down the process of digestion step by step:

### Step-by-Step Solution:

1. **Chewing and Formation of Bolus**:
- The process begins in the mouth where food is chewed and mixed with saliva, forming a soft mass called a bolus.

2. **Passage Through the Oesophagus**:
- The bolus then travels down the oesophagus to reach the stomach. It remains termed as bolus during this transit.

3. **Acidic Medium in the Stomach**:
- Once the bolus enters the stomach, it is mixed with gastric juices, which are acidic due to hydrochloric acid (HCl). At this stage, the bolus is transformed into a semi-liquid substance called chyme.

4. **Transition to the Small Intestine**:
- The chyme then moves from the stomach into the small intestine, starting with the duodenum. Here, it encounters an alkaline medium due to the secretion of bicarbonate from the pancreas.

5. **Formation of Chyle**:
- As the chyme continues through the small intestine (specifically in the jejunum and ileum), the digestion of nutrients, particularly fats, occurs. The digested fats are then emulsified and packaged into small droplets called chyle.

6. **Definition of Chyle**:
- Chyle is essentially a mixture of digested fats and proteins, which is ready for absorption into the lymphatic system.

### Final Answer:
After passing through the alkaline medium in the alimentary canal, the food bolus is called **chyle**.
