Answer 1

The correct option is A A- 3, B- 4, C- 2, D- 1, E- 5

At around 14th day of the menstrual cycle in human females egg is released from mature Graafian follicle under the influence of luteinizing hormone. This event is called as ovulation.

The fertilisation of an egg by sperm to give rise to a zygote is called as conception.

Fertilisation occurs in fallopian tubes, conception leads to pregnancy. Conception is followed by implantation i.e., attachment of fertilised egg or zygote to the wall of the uterus.

The time period between pregnancy and childbirth is called as gestation period. In humans, gestation period duration is roughly 38 weeks. During gestation period the embryo develops from a zygote. At the end of gestation period is parturition event during which child is delivered from the uterus.

Parturition is a complex process involving interplay of nervous and endocrine systems.

So, the correct answer is option A.
