Correct answer
A. A zygote or an early embryo with up to 8 blastomeres into the fallopian tube
Step-by-step solution
ZIFT stands for Zygote Intra Fallopian Transfer. According to NCERT, in this procedure, the zygote or early embryo (up to 8 blastomeres) is transferred into the fallopian tube to complete its further development. Transferring an embryo with more than 8 blastomeres into the uterus is called Intra Uterine Transfer (IUT). Transferring an ovum collected from a donor into the fallopian tube of another female is called Gamete Intra Fallopian Transfer (GIFT). Answer: A zygote or an early embryo with up to 8 blastomeres in
