Aryan took two food samples X and Y in separate test tubes. He added 2-3 drops of Benedict's solution in food sample X and heated it while he added two drops of copper sulphate solution and few drops of caustic soda solution in food sample Y. He observed that sample X turned orange while sample Y turned violet.
Which of the following is correct regarding X and Y?

Options

A. X could be egg while Y could be boiled potato.
B. X could be ripened banana while Y could be milk.
C. X could be wheat while Y could be butter.
D. X could be milk while Y could be rice.

Explanation

To solve the question regarding the food samples X and Y, we will analyze the reactions that took place in both samples based on the substances added and the color changes observed.

### Step-by-Step Solution:

1. **Identify the Tests Conducted:**
- For sample X: Benedict's solution was added and heated.
- For sample Y: Copper sulfate and caustic soda were added.

2. **Analyze Sample X:**
- Benedict's solution is a reagent used to test for reducing sugars (such as glucose).
- Upon heating, if reducing sugars are present, the solution changes color to orange or brick red.
- Since sample X turned orange, we can conclude that sample X contains reducing sugars.

3. **Analyze Sample Y:**
- The combination of copper sulfate and caustic soda is used in the Biuret test, which is a test for proteins.
- The presence of proteins causes the solution to turn violet.
- Since sample Y turned violet, we can conclude that sample Y contains proteins.

4. **Determine the Food Samples:**
- From the options provided, we need to match the identified components (sugars in X and proteins in Y) with the correct food items.
- Common sources of reducing sugars include fruits like ripened bananas.
- Common sources of proteins include milk.

5. **Conclusion:**
- Sample X (which turned orange) is likely to be a ripened banana (which contains reducing sugars).
- Sample Y (which turned violet) is likely to be milk (which contains proteins).

### Final Answer:
- Sample X contains reducing sugars (likely a ripened banana).
- Sample Y contains proteins (likely milk).
