The claim that sleep is more beneficial than wakefulness to memory is made in the very last sentence of the passage. That's why B is not really correct.
You may have been referring to this part of the third last sentence in the passage: "including one (study) demonstrating that sleep stabilizes declarative memories from future interference caused by mental activity during wakefulness." This is not really saying that sleep is more beneficial to memories than wakefulness is. Instead, it is saying that sleep makes memories more stable and protects them from interference caused by mental activity. And the sentence in lines 14–16 does not explain why that previous claim is unsustainable.
