Solution

The correct option is D Only i is correct
There are several assisted reproductive technologies (ART) which help infertile couples to have children.

In IVF (in vitro fertilisation) followed by ET (embryo transfer) method, also called test tube baby programme, ova from the female and sperm from male are collected and induced to form zygote in the laboratory. This is called in vitro fertilisation.

The zygote or early embryos (with upto 8 blastomeres) are transferred into the fallopian tube. This is termed as zygote intra fallopian transfer (ZIFT).

Embryos with more than 8 blastomeres are transferred into the uterus and not into the fallopian tube. This is called IUT (intra uterine transfer).
