Summarization should be configured on R3. All answers are wrong.

You can only do summarization of Internal routes in OSPF on the ABR. I don't think any of these options works.

Yes and thats why moving R4 and R5 to different areas would work, making R5 an ABR and able to send summary route towards R4.
