Which of the following statements is/are correct?
I. Acids are sour in taste and corrosive in nature.
II. Fruits and vegetables contain inorganic acids.
III. All bases are soluble in water.
IV. Bases produce salts with all metals.
V. Milk of magnesia is an aqueous solution of magnesium carbonate.

Options

A. II and IV only
B. I only
C. III and V only
D. I, II, III, IV and V

Explanation

To determine which statements are correct, let's analyze each one step by step:

### Step 1: Analyze Statement I
**Statement I**: Acids are sour in taste and corrosive in nature.
- **Explanation**: This statement is correct. Acids typically have a sour taste (like citric acid in lemons) and can be corrosive to metals and skin.

### Step 2: Analyze Statement II
**Statement II**: Fruits and vegetables contain inorganic acids.
- **Explanation**: This statement is incorrect. Fruits and vegetables primarily contain organic acids (like citric acid, acetic acid, etc.), not inorganic acids.

### Step 3: Analyze Statement III
**Statement III**: All bases are soluble in water.
- **Explanation**: This statement is incorrect. Not all bases are soluble in water. For example, some metal hydroxides are insoluble (like copper(II) hydroxide).

### Step 4: Analyze Statement IV
**Statement IV**: Bases produce salts with all metals.
- **Explanation**: This statement is incorrect. Bases do not react with all metals to produce salts. For example, they do not react with noble metals like gold and platinum.

### Step 5: Analyze Statement V
**Statement V**: Milk of magnesia is an aqueous solution of magnesium carbonate.
- **Explanation**: This statement is incorrect. Milk of magnesia is actually an aqueous suspension of magnesium hydroxide, not magnesium carbonate.

### Conclusion
Based on the analysis:
- **Correct Statements**: Only Statement I is correct.
- **Incorrect Statements**: Statements II, III, IV, and V are incorrect.

### Final Answer
The only correct statement is:
- **I. Acids are sour in taste and corrosive in nature.**
