Solution
Out of aluminium, copper, calcium and tin, the most reactive metal is calcium.
Explanation:
Calcium is the most reactive because it belongs to the alkaline earth metals group and occupies the highest position in the reactivity series among the given choices, meaning it loses electrons much more readily than aluminium, tin, and copper.
