Answer

To determine the richest source of protein among the given options (wheat, sago, soya bean, rice), we can analyze each option based on their protein content.

**Step 1: Analyze Wheat**
- Wheat is primarily a source of carbohydrates. While it does contain some protein, it is not the richest source compared to other options.

**Hint:** Consider the primary macronutrient that each food is known for.

**Step 2: Analyze Sago**
- Sago is also predominantly a carbohydrate source. It is derived from the sago palm and is mainly used for its starch content, not protein.

**Hint:** Think about the nutritional profile of sago and what it is typically used for.

**Step 3: Analyze Rice**
- Rice is another carbohydrate-rich food. While it does contain some protein, it is not significant enough to be considered a rich source of protein.

**Hint:** Reflect on the common uses of rice in diets and its nutrient composition.

**Step 4: Analyze Soya Bean**
- Soya bean is known for its high protein content. It is considered one of the richest plant sources of protein and also contains essential amino acids, making it a complete protein source. Additionally, it is a leguminous plant that helps in nitrogen fixation and contains vitamins, including B vitamins.

**Hint:** Consider the nutritional benefits of legumes and their role in a balanced diet.

**Conclusion:**
Based on the analysis, the richest source of protein among the options provided is **soya bean**.

**Final Answer:** Soya bean (Option number three).
