A
It would choose the path mentioned in D, because OSPF calculates Routes in the following order:
1. Intra-Area
2. Inter-Area
3. External Type 1
4. External Type 2
Because the interfaces from R2 to R3 and R4 are both in the same area, it uses the link to R4 to calculate the path because this would be an intra-area path.
