Step 1: Analyzing the behavior of materials.
- Ice has a lower density than water, so it will float on top when it melts.
- Oil is less dense than water and will float on top of water.
Step 2: Observing the options.
- (A) Option A does not correctly reflect the behavior of the substances.
- (B) Option B does not correctly depict the layering.
- (C) Option C correctly shows ice at the top, followed by oil, and water at the bottom.
- (D) Option D does not reflect the correct layering after melting.
Step 3: Conclusion.
The correct result is (C).
