It is balaned
Left side
1 Na
1 C
3 Os
1 H

Right side
CO2 + NaOH = NaHCO3 and the reaction type is synthesis ( this was already balanced)
I took out the <> to get CO2 + NaOH = NaHCO3
CO2- molar mass= 44.0095
NaOH- molar mass= 39.99710928
NaHCO3- molar mass= 84.00660928
The answer is B
Coal is formed under the ground when pressure is high and there is a lot of heat also to make coal you need dead and composed organisms put together all of this makes a lump of dark coal.
