Magnesium (Mg) is an alkaline earth metal, and the element that behaves most like magnesium among the options provided (Sr, S, Sn, Si) is strontium (Sr).

Both Mg and Sr are in the same group (Group 2) of the periodic table, which means they share similar chemical properties, such as having two valence electrons and commonly forming +2 oxidation states. The other elements listed (sulfur (S), tin (Sn), and silicon (Si)) belong to different groups and do not have similar properties to magnesium.
