Read the following statements and select the correct option.
Statement -1 : the stem tubers are the swollen ends of spcialised underground stem branches, which help in vegetative propagation of the plant.
Statement-2 : Solanum tuberosum is an example of a stem tuber which stores inulin as the main reserve food material.

Options

A. Both statements 1 and 2 are correct.
B. Statement 1 is correct but statement 2 is incorrect.
C. Statement 1 is incorrect but statement 2 is correct.
D. Both statement 1 and 2 are incorrect.

Explanation

To solve the question, we need to evaluate the two statements provided regarding stem tubers and Solanum tuberosum.

### Step-by-Step Solution:

1. **Analyze Statement 1**:
- The statement claims that "the stem tubers are the swollen ends of specialized underground stem branches, which help in vegetative propagation of the plant."
- This is true. Stem tubers, such as those found in potatoes, are indeed swollen portions of underground stems (specifically, they are modified stems) that serve as storage organs and aid in vegetative propagation.

2. **Analyze Statement 2**:
- The statement claims that "Solanum tuberosum is an example of a stem tuber which stores inulin as the main reserve food material."
- This statement is false. While Solanum tuberosum (the scientific name for potato) is indeed a stem tuber, it primarily stores starch as its main reserve food material, not inulin. Inulin is a polysaccharide made of fructose, and while it is a storage carbohydrate in some plants, it is not the main storage form in potatoes.

3. **Conclusion**:
- Based on the analysis, Statement 1 is correct, while Statement 2 is incorrect. Therefore, the correct option is that Statement 1 is true and Statement 2 is false.

### Final Answer:
- Statement 1 is correct, and Statement 2 is incorrect.
