Answer 1

The correct option is D a, b, c & d

It has been observed that by the end of the second month of pregnancy period, the foetus develops limbs and digits. Also, by the end of the first trimester (12 weeks), most of the major organs are developed, for instance, the limbs and external genital organs. The signals for parturition derives from the fully developed foetus and the placenta that further leads to mild uterine contraction referred to as foetal ejection reflex. By the end of pregnancy, the mammary glands initiate producing milk by the lactation process.

So, the correct answer is option D, a, b, c & d.
