Answer:  A. 2 Al+3FeO\rightarrow Al_2O_3+3 Fe

Explanation:

According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.

A. 2 Al+3FeO\rightarrow Al_2O_3+3 Fe

B. CH_4+2O_2\rightarrow CO_2+2H_2O

C. PCl_5+4H_2O \rightarrow 5HCl +H_3PO_4

D. FeCl_3+3NH_4OH\rightarrow Fe(OH)_3+3NH_4Cl

Thus the coefficients of 2, 3, 1 and 3 as present in 2CO_2+3H2O\rightarrow C_2H_6O+3O_2  will be same in  2 Al+3FeO\rightarrow Al_2O_3+3 Fe.
