I saw a comment on this question that stated: but & and are logical equivalents. Is this true?

Wrong Answer (D) and Right Answer (E). I can't seem to reach the understanding on how E is relevant, e.g. doesn't contain information introduced in the passage on whether or not zebra mussels can transform hazardous waste and why they would be considered hazardous waste. I chose (D) because out of all the answers it seemed like the closest to being supported, as it mentions one of the 'redeeming qualities' of zebra mussels.

I got 4 out of 5 right in this drill but got this particular questions drastically wrong. I selected B and on blind review selected C. I never felt E was correct during the drill or blind review. I do not know what I am not seeing on this particular question. I do not understand why C is incorrect. If 40% in the first group reported awaking paralyzed with a strange presence in the room, wouldn't it be correct to say 60% had not? Or is C wrong, because it only mentioned "strange presence" and excluded "paralyzed" as part of the answer? #help
