Oil is not miscible in water. It means that it is-

Options

A. Soluble
B. Insoluble
C. Hard
D. None.

Explanation

**Step-by-Step Solution:**

1. **Understanding the Term "Miscible":**
- The term "miscible" refers to two liquids that can mix together completely to form a homogeneous solution. For example, water and alcohol are miscible because they mix well.

2. **Analyzing the Given Statement:**
- The question states that "oil is not miscible in water." This means that oil does not mix with water.

3. **Interpreting "Not Miscible":**
- Since oil does not mix with water, we can conclude that oil is not soluble in water. Solubility refers to the ability of a substance to dissolve in a solvent.

4. **Identifying the Correct Option:**
- Based on the understanding that oil is not miscible in water, we can say that oil is "insoluble" in water.
- Therefore, the correct answer is that oil is insoluble in water.

5. **Eliminating Incorrect Options:**
- The other options provided (soluble, heart, none) are incorrect because:
- "Soluble" implies that oil can mix with water, which is not true.
- "Heart" is not relevant in this context.
- "None" suggests that none of the options apply, which is incorrect since "insoluble" is a valid option.

**Final Answer:**
Oil is insoluble in water.
