• A. After two months of fertilisation
• B. After one month of fertilisation
• C. After 3 weeks of fertilisation
• D. After about 7 days of fertilisation

Answer 1

The correct option is D After about 7 days of fertilisation

The fertilisation takes place by the fusion of the male and female gamete. This fertilised egg undergoes cleavage and forms the blastocyst. The fertilised egg to reach the blastocyst stage takes around 6-7 days. The zygote at the blastocyst stage gets implanted in the wall of the uterus after about 7 days of fertilisation.

Thus, the correct answer is option D.
