I think that should be sodium. Because sodium reacts even with cold water. Review: The highest reactive elements are the metals hence you can disregard carbon and oxygen. SO we end up having nickel and sodium . Nickel is far blow in the activity series compared to sodium as nickel reacts with acids and sodium reacting vigorously even with cold water. Hence sodium is more reactive.
