During Decarboxylation a negative charge appears on the alpha carbon ..... so all those compounds in which this negative charge is stabilised will undergo decarboxylation easily ....
So i think the answer will be a and b ... not sure about d .......
whats the right answer???
Which of the following compounds undergo easy decarboxylation?
(a)

I see utd...but in b), it's because of six-membered transition state.

as utd says a -ve charge appears on α-carbon which in case of C) (here) or α,β unsaturated acid is not stable.
**** α,β → β,γ then possible

In c it is bcoz of the carbonylic carbon the negative charge on the carbon is accommodated on the oxygen which is more electronegative ....
