Correct Answer

Explanation

When the ice cube melts in a glass of water filled to the brim, the water level will remain the same. This is because the ice cube displaces its own weight in water, and when it melts, it turns into an equivalent volume of water. Therefore, the total volume of water in the glass remains constant, and the water level does not change.
