The correct option is B Malformation of foetus
Thalidomide is an immunomodulatory drug. Thalidomide was first marketed in 1957 in West Germany. Shortly, after the drug was sold in West Germany, many infants were born with phocomelia or the malformation of the limbs. Only 40% of the children with this condition survived. Those subjected to thalidomide while in the womb experienced limb deficiencies in a way that the long limbs were either not developed or presented themselves as stumps.
Therefore, the correct answer is option C.
