Solution

The correct option is B law of conservation of mass
The total mass on the reactants side is $5.3 g + 6 g = 11.3 g$

The total mass on the product side which is $2.2 g + 0.9 g + 8.2 g = 11.3$ .

The mass of both reactant and product side are equal.

So, the total mass is conserved.

The correct option is $B$
