The stability of carbanions in the following is in the order of
  1. $a > c > b > d$
  2. $a > b > c > d$
  3. b > c $>$ d $>$ a
  4. d $>$ b $>$ c $>$ a

Solution

Higher is the electronegativity of atom higher will be stability of carbanion on it. Higher is the s-character, higher will be the electronegativity of atom.
