Options

B. Rashmi only
C. Akshi and Reema only
D. Akshi and Shristi only.

Explanation

To determine which student made incorrect statements, let's analyze each statement step by step:

### Step 1: Analyze Rashmi's Statement
- **Statement**: "Sodium chloride is an acidic salt whereas washing soda is a basic salt."
- **Analysis**: Sodium chloride (NaCl) is formed from a strong acid (HCl) and a strong base (NaOH), making it a neutral salt, not an acidic salt. Washing soda (Na2CO3) is indeed a basic salt.
- **Conclusion**: Rashmi's statement is **incorrect**.

### Step 2: Analyze Akshi's Statement
- **Statement**: "The aqueous solution of sugar does not change the colour of either red litmus solution or blue litmus solution."
- **Analysis**: A sugar solution is neutral and does not affect litmus paper, meaning it will not change the color of either red or blue litmus.
- **Conclusion**: Akshi's statement is **correct**.

### Step 3: Analyze Reema's Statement
- **Statement**: "Tamarind tastes sour whereas baking soda is bitter in taste."
- **Analysis**: Tamarind contains tartaric acid, which gives it a sour taste. Baking soda (sodium bicarbonate) is indeed bitter.
- **Conclusion**: Reema's statement is **correct**.

### Step 4: Analyze Shristi's Statement
- **Statement**: "Apple juice does not change the colour of red litmus solution."
- **Analysis**: Apple juice is acidic and would turn blue litmus paper red, but it does not affect red litmus paper (it remains red).
- **Conclusion**: Shristi's statement is **correct**.

### Final Conclusion
The only incorrect statement is made by Rashmi. Therefore, the answer is that the incorrect statement(s) is/are given by **Rashmi**.
