Best answer
Right answer is (a) small

To elaborate: In case of pre-consolidated soil, the final settlement is small. This is because, the recompression index or the swelling index Cs is very small in comparison to the compression index Cc. The pre-consolidated soil has been subjected to large overburden loads in the past.
