In which of the following arrangements, the sequence is not strictly according to the property written against it?

• A. \[C{{O}_{2}}<Si{{O}_{2}}<Sn{{O}_{2}}<Pb{{O}_{2}}\]: increasing oxidising power
• B. \[N{{H}_{3}}<P{{H}_{3}}<As{{H}_{3}}<Sb{{H}_{3}}:\] increasing basic strength
• C. \[HF<HCl<HBr<HI:\] increasing acid strength
• D. \[B<C<O<N:\] increasing first ionisation enthalpy.
