Answer 1

Gestation is nothing but a pregnancy where women carries one or more fetus in her womb, and sometimes, there will be more than one fetus at a time such as twins, and it is mainly occurred by sexual intercourse, or assisted reproductive technology.

Complete answer:
- Pregnancy results in the live birth of the child, and sometimes there may be spontaneous bleeding or stillbirth may occur because of various reasons.
- Typically this pregnancy or gestation lasts for 9 months, if we take 31 days for a month also, it is around 38 weeks. And it is called gestation age.
- There are some early signs and symptoms present at the time of gestation, such as vomits, breast tenderness, missed periods, frequent urination, etc.
- Gestational age is the starting point or the beginning of the women last menstrual period.
- The total gestation is divided into 3 trimesters.
- 1st trimester: This is calculated from the beginning of gestation age and last up to 12th week, this is most important period of the gestation, where, fertilization, and formation of embryo and all the place in the 1st trimester, women should be very careful because most of the miscarriages occur in the 1st trimester.
- The 2nd trimester begins from the 13th week of the gestation and it lasts up to 27th week.
- 3rd trimester begins at the 28th week and lasts up to childbirth.

Hence, the correct answer is option (B).

Note: During gestation, there are so many physiological morphological changes can be seen in the women body and there may be changes in the behaviour and other organ systems and there is continuous increase in progesterone and estrogen levels in the body.
