When dealing with oxidation-reduction equations, just remember the mnemonic OIL RIG. OIL = oxidation is losing, RIG = reduction is gaining. So this question is asking what is losing electrons, and thus gaining a positive charge?
We know that Chlorine always has a -1 charge, and Hydrogen always has a +1 charge. In this equation, the Mn is losing 2 electrons (becoming positive) so that it can bind to the 2 Cl.
Short answer, Manganese is oxidized in this equation.

Verified answer
Mn + HCl → MnCl2 + H2
The balanced reaction is:
Mg(s) + 2HCl(aq) → MgCl2(aq) + H2(g)
Here, Mg goes from the 0 to the 2 oxidation state by losing two electrons.
hence in the above reaction Mg is oxidized.
