现已知：\(\rm{2H_{2}(g)+O_{2}(g)=2H_{2}O(l)}\)，\(\rm{\triangle H=-572kJ/mol}\)；\(\rm{H-H}\)键的键能为\(\rm{436kJ/mol}\)；\(\rm{O=O}\)键的键能为\(\rm{498kJ/mol}\)，则\(\rm{H_{2}O}\)分子中\(\rm{O-H}\)键的键能为\(\rm{(}\)　　\(\rm{)}\)

A．\(\rm{485.5kJ/mol}\)

B．\(\rm{610}\) \(\rm{kJ/mol}\)

C．\(\rm{917}\) \(\rm{kJ/mol}\)

D．\(\rm{1220}\) \(\rm{kJ/mol}\)
