As we learnt in 

Cannizzaro's reaction -

Shown by aldehydes which do not have \alpha- H atom and undergo disproportion (self-oxidation reduction) process to produce alcohol and carboxylic acid salt.

- wherein

2HCHO\overset{conc.NaOH}{\rightarrow}HCOONa+CH_{3}OH

 

 It is a cannizzaro reaction

Thus, A is an aldehyde without \alpha -hydrogen \: atom
