Among the hydrides formed by the group VI-A elements, only \[{{H}_{2}}O\] has an abnormally low volatility (high boiling point). This is so because

A) \[{{H}_{2}}O\] molecules are associated due to intermolecular hydrogen bonds

B) \[{{H}_{2}}O\] is covalent in nature

C) The \[O-H\] bond in \[{{H}_{2}}O\] is very strong

D) The electronegativity difference of \[H\] and \[O\] is very large
