The correct option is B Artificial introduction of sperms of a healthy donor into the cervix
Artificial insemination (AI) is the deliberate introduction of sperm into a female's cervix or uterine cavity for the purpose of achieving a pregnancy through in vivo fertilization by means other than sexual intercourse or in vitro fertilisation. It is also called Intrauterine Inseminaion (IUI). The sperm used in artificial insemination may be provided by either the woman's husband or by a known or anonymous sperm donor.
