(A) The statement that $Helium$ is used in balloons because it is lighter than $Hydrogen$ is incorrect. $Helium$ is actually heavier than $Hydrogen$ ($Molar \ mass \ of \ He = 4 \ g/mol$ while $Molar \ mass \ of \ H_2 = 2 \ g/mol$). However,it is preferred over $Hydrogen$ because it is non-inflammable and safe,whereas $Hydrogen$ is highly inflammable.
