Otherwise, they would be detained or sent back to Europe. The possibility of this happening made many immigrants anxious. Option B paraphrases this information best.
Option A is incorrect because Ellis Island isn't called Heartbreak Island because of medical issues people had there.

Option D doesn't tell us what Ellis Island is, and immigrants who didn't pass examinations weren't sent to live there.
