Water exist in

Options

A. gaseous phase
B. liquid phase
C. solid phase
D. All of these

Explanation

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks in which forms water exists. We need to identify the different phases or states of water.

2. **Identifying the Phases of Water**: Water can exist in three distinct phases:
- **Solid Phase**: This is when water is in its solid form, commonly known as ice.
- **Liquid Phase**: This is the form we are most familiar with, which is liquid water.
- **Gaseous Phase**: In this phase, water exists as steam or water vapor.

3. **Analyzing the Options**: The options provided are:
- A) Solid phase
- B) Liquid phase
- C) Gaseous phase
- D) All of these (solid, liquid, and gas)

4. **Determining the Correct Answer**: Since water can exist in all three phases (solid, liquid, and gas), the correct answer is:
- **Option D: All of these**

5. **Conclusion**: Therefore, the answer to the question "Water exists in" is option D, which means water exists in solid, liquid, and gaseous forms.
