The correct answer is:
B. Steam has more energy than water.
**Explanation:**
While both water and steam can exist at the same temperature of 100 degrees Celsius, steam has a higher energy content due to its phase being gaseous rather than liquid. This is because steam has undergone a phase change from liquid to gas, which requires additional energy (known as latent heat of vaporization). Therefore, at 100 degrees Celsius, steam has more energy than liquid water at the same temperature.
