The correct answer is 3. Fizzing. When a metal reacts with water, it often produces hydrogen gas, which can cause bubbling or fizzing in the water. This is usually the most obvious way to tell that a metal is reacting with water. However, if the metal is very reactive, it may also produce a bright light or get hot enough to boil the water. A color change is less likely, unless the metal is dissolving to produce a colored solution.
