Which of the following statements is correct?
A. Water is compound.
B. Water has maximum density at 4°0.
C. Water is a polar compound and it is universal solvent.

Options

A. A and C
B. A and B
C. B and C
D. All of these

Answer

To determine which of the statements about water is correct, let's analyze each option step by step.

### Step 1: Analyze Statement A
**Statement A:** Water is a compound.
- Water has the chemical formula H₂O, which indicates that it is composed of two hydrogen atoms and one oxygen atom. Since it is made up of two different elements, hydrogen and oxygen, it qualifies as a compound.

**Conclusion:** Statement A is correct.

### Step 2: Analyze Statement B
**Statement B:** Water has maximum density at 4°C.
- Water exhibits unique properties, one of which is that it reaches its maximum density at 4°C. Below and above this temperature, water becomes less dense. This is why ice floats on water.

**Conclusion:** Statement B is correct.

### Step 3: Analyze Statement C
**Statement C:** Water is a polar compound and it is a universal solvent.
- Water is indeed a polar molecule due to the difference in electronegativity between hydrogen and oxygen, leading to a partial positive charge on the hydrogen atoms and a partial negative charge on the oxygen atom. This polarity allows water to dissolve many substances, earning it the title of "universal solvent."

**Conclusion:** Statement C is correct.

### Final Conclusion
All three statements (A, B, and C) about water are correct. Therefore, the correct answer to the question is that all statements are true.
