As we learnt,

Distillation of calcium salt of fatty acid leads to the formation of ketone

\mathrm{(RCOO)_{2}Ca\rightarrow RCOR+CaCO_{3}}

Thus the given reaction forms pentan-3-one as given below

 \mathrm{\left ( CH_{3}CH_{2}COO \right )_{2}Ca\overset{\bigtriangleup }{\rightarrow}CH_{3}CH_{2}COCH_{2}CH_{3}+CaCO_{3}}

Therefore, the correct answer is Option (3)
