Aarushi took two food samples X and Y in separate test tubes. She added 2-3 drops of Benedict's solution in food sample X and heated it while she added two drops of copper sulphate solution and few drops of caustic soda solution in food sample Y and kept the setup for few minutes. She observed that sample X turned brick-red while sample Y turned purple.
Which of the following is correct regarding X and Y?

Options

A. X consists of protein while y consists of starch.
B. X consists of sugar while Y consists of protein.
C. X consists of starch while Y consists of protein
D. X consists of sugar while Y consists of starch.

Explanation

To solve the question regarding Aarushi's food samples X and Y, we need to analyze the results of the tests she performed on each sample.

### Step-by-Step Solution:

1. **Identify the Tests Conducted**:
- For sample X, Aarushi added Benedict's solution and heated it.
- For sample Y, she added copper sulfate and caustic soda.

2. **Analyze Sample X**:
- The addition of Benedict's solution and heating resulted in a brick-red color.
- The brick-red color indicates the presence of reducing sugars (like glucose or fructose) in the sample. Benedict's test is specifically used to detect reducing sugars.

3. **Analyze Sample Y**:
- The addition of copper sulfate and caustic soda resulted in a purple color.
- The purple color indicates the presence of proteins. This test is known as the Biuret test, which is used to detect proteins.

4. **Conclusion**:
- Based on the observations:
- Sample X contains reducing sugars (indicating it is a carbohydrate).
- Sample Y contains proteins.

5. **Select the Correct Option**:
- The correct statement based on the analysis is:
- **Option 2: X consists of sugar while Y consists of protein.**
