a father has Y with say A so YA. so the male child get YA.type of HLA. if we give him the graft from
chiocie D malechild of YA father. he has YA too. so it would be accepted.
so I go for D

i say D just cuz it's the same genetic make-up as the host! (hence increase change of graft success)
host: male (AXB)F1 mouse with strain A father and strain B mother
donor in answer D: (AXB) F1 male (A. father B mother)
It seems like the natural answer to me!

I will go for B.
The incompatability is on Y and if the recipent is a female, then, she couldent mount an incomatable gene as she doesent have Y.
