Correct Answer: Option C
Explanation

MnO\(_2\)(s) + xHCl(aq) → MnCl\(_2\)(aq) + yH\(_2\)O(l) + zCl\(_2\)(g)

First, balance the chemical equation, then equate each of the letters with the coefficients.

On balancing, we have :  MnO\(_2\)(s) + 4HCl(aq) → MnCl\(_2\)(aq) + 2H\(_2\)O(l) + Cl\(_2\)(g)

Therefore, x = 4,y = 2 and z = 1

There is an explanation video available below.
