Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Relaxin is produced first by the corpus luteum of the ovary and later by the placenta. It helps in parturition as it increases the flexibility of the pubic symphysis and helps dilate the uterine cervix.

Questions Asked in NEET exam
- Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R.
Assertion A : The potential (V) at any axial point, at 2 m distance(r) from the centre of the dipole of dipole moment vector \(\vec{P}\) of magnitude, 4 × 10-6 C m, is ± 9 × 103 V.
(Take \(\frac{1}{4\pi\epsilon_0}=9\times10^9\) SI units)
Reason R : \(V=±\frac{2P}{4\pi \epsilon_0r^2}\), where r is the distance of any axial point, situated at 2 m from the centre of the dipole.

Pregnancy
The human gestation period or pregnancy lasts for over nine months or 266 days. At times, childbirth also takes place prematurely or even after nine (9) months. The entire process of pregnancy is split into trimesters of three intervals:
- First Trimester: This comprises the period mainly from week one to twelve. This is the embryonic or pre-embryonic development stage.
- Second Trimester: This comprises the period from week thirteen to the twenty-fourth. This is the stage of fetal development and normally, most the body parts develop in this stage.
- Third Trimester: This comprises the period from week twenty-fifth to that of the birth of an infant. This stage spectates some of the major developments in the child such as the formation of the blood cells, bones turning hard, sense organs being developed and the fingernails are also visible by this stage.
