What mass of hydrogen and oxygen will be produced on complete electrolysis of 18g of water?

2g hydrogen and 32g oxygen

2g hydrogen and 16g oxygen

4g hydrogen and 32g oxygen

4g hydrogen and 14g oxygen

2g hydrogen and 16g oxygen

The balanced chemical equation for electrolysis can be written as:
2H2?O→2H2?+O2?
Now 36g of H2?O gives = 4g of H2? and 32g of O2?
Therefore 18g of H2?O gives = 2g of H2? and 16g of O2?
