ZIFT stands for Zygote Intra Fallopian Transfer. This is a technique used in assisted reproductive technologies where a fertilized egg (zygote) is directly transferred into the fallopian tube, rather than the uterus, to facilitate implantation and pregnancy.
The process is typically used when there are issues with the uterus that prevent successful implantation or when in vitro fertilization (IVF) has been performed.
The correct answer is (B) : Zygote Intra Fallopian Transfer.
The correct answer is: (B) Zygote Intra Fallopian Transfer.
ZIFT stands for Zygote Intra Fallopian Transfer, which is an advanced technique in assisted reproduction. It is often used in cases of infertility where other methods like In Vitro Fertilization (IVF) or Gamete Intra-Fallopian Transfer (GIFT) are not successful or feasible. In this procedure, fertilization occurs outside the woman’s body, in a laboratory, and once the egg is fertilized to form a zygote, it is transferred into the fallopian tube instead of the uterus.
This technique has the advantage of allowing the embryo to develop in the natural environment of the fallopian tube, where it can then travel to the uterus and implant. Unlike traditional IVF, which places the embryo directly into the uterus, ZIFT gives the zygote the ability to undergo its first stages of development within the fallopian tube.
ZIFT is commonly recommended in cases of blocked fallopian tubes or when there are issues with the uterine environment that may make embryo implantation challenging. The success rates of ZIFT vary, and the procedure often involves hormonal stimulation of the ovaries, egg retrieval, fertilization, and subsequent transfer of the zygote.
Therefore, the correct abbreviation for ZIFT is Zygote Intra Fallopian Transfer, and it is a significant option in the field of fertility treatments.

You are given a dipole of charge \( +q \) and \( -q \) separated by a distance \( 2l \). A sphere 'A' of radius \( R \) passes through the centre of the dipole as shown below and another sphere 'B' of radius \( 2R \) passes through the charge \( +q \). Then the electric flux through the sphere A is
