The correct choice is (a) normally consolidated

For explanation: A normally consolidated specimen is one which has never been subjected to an effective pressure greater than the existing overburden pressure. Thus, a clay is said to be pre-consolidated, over- consolidated or pre- compressed if it has been subjected to a pressure in excess of its present overburden pressure.
