Sure, let's break down the question step by step:

1. **Understanding the Question**: The question is asking which structure in the small intestine is responsible for absorbing nutrients from food and passing them on to the rest of the body.

2. **Analyzing the Options**:
- **a) Villi**: These are small, finger-like projections that line the walls of the small intestine. They increase the surface area for absorption and contain blood vessels that help in transporting absorbed nutrients.
- **b) Blood cells**: These are cells found in the blood, such as red blood cells and white blood cells. They are not directly involved in the absorption of nutrients in the small intestine.
- **c) Haustra**: These are pouches found in the large intestine, not the small intestine. They help in the movement and absorption of water and salts, but not nutrients from food.
- **d) Sub-mucosa**: This is a layer of tissue in the gastrointestinal tract, located beneath the mucosa. It contains blood vessels, nerves, and glands, but it is not directly responsible for nutrient absorption.

3. **Conclusion**: Based on the analysis, the correct answer is:
- a) Villi
