  We derive the canonical (anti-)commutation relations amongst the creation and
annihilation operators of the various basic fields, present in the four (3 +
1)-dimensional (4D) free Abelian 2-from gauge theory, with the help of
continuous symmetry transformations within the framework of
Becchi-Rouet-Stora-Tyutin (BRST) formalism. We show that all the six continuous
symmetries of the theory lead to the exactly the same non-vanishing
(anti-)commutator amongst the creation and annihilation operators of the normal
mode expansion of the basic fields of the theory.
