Highly REACTIVE metals above -ldots (1) in the reactivity series are extracted by -... (2) 1: hydrogen; 2:reduction 1; carbon; 2: electrolysis 1: hydrogen; 2:electrolysis 1: carbon; 2: reduction

## Step 1: Identify the highly reactive metals in the reactivity series.Highly reactive metals are those that are found at the top of the reactivity series.## Step 2: Determine the position of hydrogen and carbon in the reactivity series.Hydrogen is below many metals like sodium, potassium, calcium, etc., while carbon is also below these highly reactive metals but above hydrogen.## Step 3: Identify the method used for extracting highly reactive metals.Highly reactive metals are typically extracted by electrolysis because they are too reactive to be reduced by carbon or hydrogen.## Step 4: Match the correct pair from the given options.- Option 1: - Incorrect because highly reactive metals are not extracted by reduction.- Option 2: - Correct because highly reactive metals above carbon in the reactivity series are extracted by electrolysis.- Option 3: - Incorrect because it should be carbon, not hydrogen.- Option 4: - Incorrect because highly reactive metals are not extracted by reduction.#
