Correct : b

Ramya said to Josephine: "Even if I had known that you were in the hospital, I would not have gone there to see you."

The phrase "Even if I had known..." is a past unreal conditional, which means that in reality she did not know about it. The rest of the sentence simply states that even with the knowledge, she still would not have gone.

Therefore, the only logically correct inference is that Ramya did not know that Josephine was in the hospital.

✅ Final Answer: Option (b) — Ramya did not know that Josephine was in the hospital.

Reason: The statement structure implies the condition was not true in reality, so the knowledge about Josephine’s hospitalization was absent.
