Match the columns:

Column $1$	Column $2$	Column $3$
$(a) ZIFT$	$(p) ART$ method	$(w)$ Ovum and sperm in fallopian tube
$(b) ART$	$(q) ZIFT$	$(x)$ Embryo with more than $8$ blastomeres in uterus
$(c) GIFT$	$(r) IVF$	$(y)$ Embryo with up to $8$ blastomeres in fallopian tube
$(d) IVF$	$(s) GIFT$	$(z)$ Ovum transfer into fallopian tube

(A) The correct matches are:
$a-q-y$: $ZIFT$ ($Zygote$ $Intra$ $Fallopian$ $Transfer$) involves the transfer of an embryo with up to $8$ blastomeres into the fallopian tube.
$b-p$: $ART$ ($Assisted$ $Reproductive$ $Technology$) is the umbrella term for these methods.
$c-s-z$: $GIFT$ ($Gamete$ $Intra$ $Fallopian$ $Transfer$) involves the transfer of an ovum collected from a donor into the fallopian tube of another female.
$d-r-x$: $IVF$ ($In$ $Vitro$ $Fertilization$) followed by $ET$ ($Embryo$ $Transfer$) involves transferring an embryo with more than $8$ blastomeres into the uterus.
Therefore,the correct sequence is $a-q-y, b-p, c-s-z, d-r-x$.
