In which of the following techniques, fertilisation occurs outside the female body?

The correct option is B

IVF and ICSI

IVF is the process of fertilization by manually combining an egg and sperm in a laboratory dish, and then transferring the embryo to the uterus. Intra-cytoplasmic sperm injection (ICSI) differs from conventional in vitro fertilisation (IVF) in that the embryologist selects a single sperm to be injected directly into an egg, instead of fertilisation taking place in a dish where many sperm are placed near an egg. In both these cases fertilization occurs outside the female body.
