Option: 1 ZIFT and IUT
 
Option: 2 GIFT and ZIFT
 
Option: 3 ICSI and ZIFT
 
Option: 4 GIFT and ICSI

ZIFT - Zygote Intra-Fallopian tube  Transfer is a form of assisted reproductive technology (ART). In this technique, we are going to put the zygote which has started developing into the embryo in the fallopian tube rather than in the uterus and we will wait for it to travel the whole length of the fallopian tube and reach the uterus on its own. On the other hand, IUT (Intrauterine transfer) is a technique in which embryos are placed into the uterus of a female with the intent to establish a pregnancy. 

Hence, the correct option is (a).
