Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question states that many salts absorb water from the atmosphere. We need to identify the property that describes this behavior.

2. **Analyzing the Options**:
- **Option A: Hydration**: Hydration refers to the process where water molecules are added to a substance. This does not apply here as we are discussing salts absorbing water from the atmosphere, not adding water to them.
- **Option B: Dehydration**: Dehydration is the removal of water from a substance. This is the opposite of what is being described in the question, so this option is also incorrect.
- **Option C: Deliquescence**: Deliquescence is the process by which a substance absorbs moisture from the atmosphere to the extent that it can dissolve in the absorbed water. This matches the description given in the question.

3. **Conclusion**: Based on the analysis of the options, the correct answer is that the property of many salts absorbing water from the atmosphere is called **deliquescence**.
