Solution
The correct option is C Zinc
Zinc (Zn) is the most preferred metal in the laboratory because metals like potassium (K) and sodium (Na) react violently with acid because of their high reactivity. Also, unlike zinc, metals like magnesium (Mg) and calcium (Ca) are expensive. Thus, overall, zinc is the most preferred metal in the laboratory to prepare hydrogen by means of metals reacting with acids.
