Does the equation below follow the Law of Conservation of Matter?

2As + 6NaOH --> 2Na3AsO3 + NH2

a
Yes, because the reactants contain the same number of arsenic (As) atoms as the products.
b
No, because the reactants contain more oxygen (O) atoms than the products.
c
No, because the reactants contain more hydrogen (H) atoms than the products.
d
Yes, because the mass of the reactants is equal to the mass of the products.

d
