2. **Identifying the Function of Nodulated Roots:**
- The primary function of nodulated roots is to form a symbiotic relationship with nitrogen-fixing bacteria. These bacteria convert atmospheric nitrogen (N2) into forms that plants can use, such as amino acids.

3. **Recognizing the Plant Groups with Nodulated Roots:**
- Nodulated roots are primarily found in legumes, which belong to the family Leguminosae. This family includes a variety of plants that have the ability to fix nitrogen due to their nodulated roots.

4. **Analyzing the Given Options:**
- The options provided are:
- A) Apple
- B) Mustard
- C) Pulses
- D) Mango
- We will evaluate each option to determine if they belong to the legume family.

5. **Evaluating Each Option:**
- **Option A: Apple**
- Apple belongs to the Rosaceae family. Therefore, it does not have nodulated roots.
- **Option B: Mustard**
- Mustard belongs to the Brassicaceae family. Thus, it also does not have nodulated roots.
- **Option C: Pulses**
- Pulses are legumes and belong to the Leguminosae family. They are known for having nodulated roots, making this option correct.
- **Option D: Mango**
- Mango belongs to the Anacardiaceae family. Hence, it does not have nodulated roots.

6. **Conclusion:**
- Based on the analysis, the correct answer is **C) Pulses**. They are the only option that has nodulated roots due to their classification as legumes.
