Which species are more resonance stabili...

Which species are more resonance stabilized in the following pairs:
`[C_(6)H_(5)Cl, C_(6)H_(5)CH_(3)], [CH_(2)=CHCl, CH_(2)=CHCH_(2)Cl]`,
`[C_(6)H_(5)Br, C_(6)H_(5)CH_(2)Br], [CH_(3)COOH, CH_(3)COO^(-)]`

A

`C_(6) H_(5) Cl , CH_(2)= CH CH_(2) Cl , C_(6) H_(5) CH_(2) Br, CH_(3) COO^(-)`

B
