Answer 1

Abortion can be defined as termination of a pregnancy by removal of an embryo or foetus using surgical methods. An abortion can occur spontaneously without intervention and iscalled a miscarriage. Infertility means the inability to conceive a baby, despite frequent and unprotected sexual intercourse for at least a year. Lactation is the process of production of milk by the mammary glands at the end of pregnancy. During breastfeeding, the ovulation process is delayed.

Complete explanation:
Let’s solve this question by observing the trueness of the given statements.
Statement (i):The given statement “abortion could happen spontaneously too” is true. Spontaneous abortion is also known as miscarriage and it occurs before ${20^{th}}$ week due to underdevelopment of the foetus.
Statement (i) is correct.
Statements (ii): Infertility means the inability to produce offspring due to some health problems in both men and women. In men, decreased sperm production and sperm viability can lead to infertility. Infertility is not only because of women.
Statement (ii) is incorrect.
Statement (iii):Lactation and exclusive breastfeeding to the baby for six months can act as a temporary contraceptive in mothers. This is because lactation delays the ovulation process.
Statement (iii) is correct.
Statement (iv): This statement is true because creating sexual awareness can help prevent STDs, unnecessary pregnancies in individuals and create a healthy society.
Statement (iv) is correct.
Now based on the observations, option C is correct as it confers statements –(i),(iii) and (iv) as true and (ii) as false.

Hence the Correct answer is option C. (i) T (ii) F (iii) T (iv) T

Note:
Lactation prevents pregnancy by disrupting the release of gonadotropin releasing hormone from the hypothalamus and hence luteinizing hormone from the pituitary. This condition is called lactational amenorrhea or postpartum infertility. Infertility in men can be due to low sperm production, blockages that prevent the sperm delivery or lesser sperm viability.
