The correct answer is D. 1978.

Louise Brown was the first baby born as a result of in vitro fertilisation (IVF). She was born on 25 July 1978 in Oldham, England. Her parents, Lesley and John Brown, had been trying to conceive for nine years before they underwent IVF treatment.

IVF is a process in which eggs are removed from a woman’s ovaries, fertilised with sperm in a laboratory, and then implanted back into the woman’s womb. Louise Brown was conceived using this technique.

Her birth was a landmark event in the history of medicine. It showed that IVF was a safe and effective way to help couples who were unable to conceive naturally. Since Louise Brown’s birth, millions of babies have been born using IVF.
