B. All minerals cannot be an ore
C. All ores are minerals
D. The minerals from which metals can be extracted profitably are called ores

Answer

To solve the question "Pick up the correct statement(s):", we will analyze each option based on the definitions of minerals and ores.

### Step-by-Step Solution:

1. **Understanding Definitions**:
- **Minerals**: Naturally occurring substances found in the Earth's crust that contain metals.
- **Ores**: Specific types of minerals from which metals can be extracted profitably and conveniently.

2. **Analyzing Each Option**:
- **Option 1: All minerals are ores.**
- This statement is **false**. Not all minerals can be economically extracted for metal; only specific ones qualify as ores.

- **Option 2: All minerals cannot be an ore.**
- This statement is **true**. Since not every mineral is suitable for profitable extraction, this is correct.

- **Option 3: All ores are minerals.**
- This statement is **true**. By definition, ores are a subset of minerals that can be profitably extracted.

- **Option 4: The minerals from which metal can be extracted profitably are called ores.**
- This statement is **true**. This is the correct definition of ores.

3. **Conclusion**:
- The correct statements are **Option 2, Option 3, and Option 4**.

### Final Answer:
The correct statements are:
- Option 2: All minerals cannot be an ore.
- Option 3: All ores are minerals.
- Option 4: The minerals from which metal can be extracted profitably are called ores.
