Entropy of universe is:

Options

A. Increasing
B. decreasing
C. Constant
D. None of these

Answer

To solve the question regarding the entropy of the universe, we can break it down into several steps:

### Step-by-Step Solution:

1. **Understanding Entropy**:
- Entropy is a measure of disorder or randomness in a system. In thermodynamics, it is often associated with the amount of energy in a physical system that is not available to do work.

2. **Second Law of Thermodynamics**:
- According to the second law of thermodynamics, the total entropy of an isolated system can never decrease over time. It can only increase or remain constant in ideal cases.

3. **Entropy of the Universe**:
- The universe can be considered as an isolated system. Therefore, the entropy of the universe must follow the second law of thermodynamics.

4. **Direction of Energy Flow**:
- Energy tends to flow from regions of higher energy (hot) to regions of lower energy (cold). This spontaneous flow contributes to the increase in entropy.

5. **Conclusion**:
- Since the universe is constantly evolving and energy is spreading out, the overall entropy of the universe is always increasing.

### Final Answer:
The entropy of the universe is **increasing**.
