C. 100 ml to 500 ml
D. 10 ml to 15ml

Answer

**Step-by-Step Solution:**

1. **Understanding Gastric Juice Production**: The stomach secretes gastric juice, which is essential for digestion. This secretion occurs throughout the day, particularly when food is ingested.

2. **Amount of Gastric Juice**: The average amount of gastric juice secreted by the human stomach per day is approximately between 1200 to 1500 milliliters (ml).

3. **Source of Gastric Juice**: Gastric juice is secreted from the gastric mucosa, which is the mucous membrane lining the stomach.

4. **Composition of Gastric Juice**: The gastric juice consists of several components:
- Hydrochloric acid (HCl)
- Mucus
- Digestive enzymes

5. **Function of Gastric Juice**: When food enters the stomach, it combines with gastric juice. This mixture transforms the food (bolus) into a semi-liquid substance known as chyme through a process called churning.

6. **Conclusion**: Based on the information provided, the amount of gastric juice secreted per day from a man's stomach is approximately 1200 to 1500 ml.

**Final Answer**: The amount of gastric juice secreted per day from man's stomach is about 1200 to 1500 ml.
