The  reaction that would result  in formation  of gaseous product  is


KHCO3  +  HBr  ( third  answer)


explanation

KHCO3  react with  HBr  to form  KBr ,  CO2  and H2O  according  to  the  below equation.


KHCO3 + HBr →  KBr  + CO2 + H2O

CO2 ( carbon (IV)  oxide)  is the gas that  is  formed   during   reaction.


other reaction does not produce a   a gas for example  NaOH +   HCl forms  NaCl  and H2O
