Solution

The correct option is B Fifth month
The third month of pregnancy is marked by large foetus head, slow down of head growth, an increase in the length of rest body, initiation of the process of ossification i.e., replacement of cartilage with bone. The fourth month of pregnancy is characterised by the presence of visible skeleton, beginning of the appearance of hair on head and experience of foetal movement by a mother who has previously been pregnant. This makes options B and C incorrect as hair are absent before the fourth month. The fifth month of pregnancy is marked by deposition of protective cheesy coating called as vernix caseosa, commencement of hair on head and experience of foetal movement by a mother who has not been previously pregnant. This makes option D incorrect and A correct as foetus movement during the fifth month is intense enough to be felt by a first-time mother. The sixth month is marked by presence pink and wrinkled skin all over the body which in turn is covered by fine hair called as lanugo.
Thus, option A is the correct answer.
