• D. Fertilisation as well as embryo development take place under laboratory condition i.e, outside mother's womb.

Answer 1

Answer: (A), (C)

The correct options are
A <!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> In vitro fertilisation (IVF) is an option for women to produce their own child who cannot reproduce naturally .
C The zygote is allowed to develop through fertilisation in laboratory for about a week and then implanted in the mother’s uterus.

In some cases, women cannot reproduce naturally due to blockage of oviducts. Hence, sperms cannot reach the egg for fertilisation and women become unable to give birth to babies. In vitro fertilisation (IVF) is an option for such cases. During in vitro fertilisation:

• Doctors collect freshly released egg and sperm and allow them to fertilise by keeping them together under laboratory conditions for few hours.
• Fertilisation occurs and the zygote is allowed to develop for about a week and then it is implanted in the mother’s uterus for complete development of embryo.
• The baby is born like any other baby and babies born through this technique are called test-tube babies.
