you're not wrong, but I think it's better to have put O-negative because that's the preferred type of RBC for transfusion unless you've type and crossed your patient

I think fetus is O+ but if you give them that the RBCs will still be destroyed. You want to give O- as it wont get destroyed and wont affect the fetus in any way. Similar mechanism to giving platelets to someone with TTP, HUS, etc. they just get destroyed so its useless

In utero, should give O- to avoid mom attacking again. After birth, O+ probably better.

I thought the O, Rh-negative blood was universal for Blood Cell transfuion, while AB, Rh-Positive was the universal for blood plasma (Since it lacks Ab to A,B, and Rh+ cells)

Not sure why you're getting downvoted, but this makes sense to me.
Maybe because you're claiming that the fetus is Rh+ when it's not clearly stated? But take that away and your explanation still makes sense.

the question is not asking what to give to the mother.
it's asking what to give to the fetus.

Mother is Rh-neg --> she will generate RH-antibodies 1) fetus affected by Anti-Rh if it is Rh-positive 2) even if O-Rh-Positive is given, then still mother's Rh-antibodies will attack transfused blood due to its cells containing Rh+ 3) therefore, O-Rh-negative is best
