Correct answer · Option A

Gametogenesis → Insemination → Fertilisation → Implantation → Gestation → Parturition

Explanation

The correct sequence of reproductive events in humans is: Gametogenesis (formation of gametes) → Insemination (transfer of sperms into female genital tract) → Fertilisation (fusion of gametes to form zygote) → Implantation (attachment of blastocyst to uterine wall) → Gestation (embryonic development) → Parturition (delivery of the baby).
