C. The pathogen is attacked by memory B cells.
D. The pathogen has been weakened.
I don’t want to sound rude, but have you read the appropriate chapter in your text? Even a very quick reading of the chapter on the immune system should let you answer the vast majority of these questions very easily.
If there are still questions you don’t understand, ask about them, and I’m sure we can help. But I don’t think I should do your homework for you.
