reaction with NaHCO3 and evolution of CO2 gas is the test for carboxylic acids
so the compounds should be carboxylic acids
options b and c contain aldehydes which do not produce a gas upon reaction with NaHCO3
now look at a and d
we have
acetic acid has a forumla C2H3O2
propanoic acid has formula C3H6O2
butanoic acid and 2-methylpropanoic acid has formula C4H8O2
so
the answer is d) butanoic acid and 2-methylpropanoic acid
