electrolysis
Explanation
## Step 1:The question asks us to identify the method used to extract more reactive metals, such as aluminum, from their ores. The options given are 'electrolysis', 'hydrolysis', 'reduction in a blast furnace', and 'oxidation'.## Step 2:We need to understand the extraction methods for metals. More reactive metals cannot be extracted by simple reduction methods because they form stable compounds.## Step 3:Aluminum is a highly reactive metal. The common method to extract highly reactive metals like aluminum is through electrolysis. This process involves passing an electric current through the molten ore to separate the metal.## Step 4:The other options, 'hydrolysis', 'reduction in a blast furnace', and 'oxidation', are not suitable for extracting highly reactive metals. Hydrolysis involves water and is not used for metal extraction. Reduction in a blast furnace is used for less reactive metals like iron. Oxidation is not a method of extraction but rather a process where metals react with oxygen.#
