Solution

The correct option is C Displacement reaction
The reaction $M g (s) + 2 H C l \to M g C l_{2} + H_{2}$ represents a displacement reaction. $M g$ metal displaces hydrogen from $H C l$ .
Note:
In a displacement reaction, a more reactive element displaces a less reactive element from its salt solution.
