B is true, but I’ve seen some crazy long fallbacks before.

Wait, C is misleading. Fallback is for receiving Ether, not avoiding it.

Okay, I think the answer is B. The question is asking about what's required, and it says we should use data connections that support multiple sources, rather than just single source connections. That makes sense to me.

This seems like a straightforward question about the advantages of using adaptive time thresholds. I'll need to carefully read through the options to understand the key differences.

Yes, I think regular password changes are crucial, but I'm not completely certain about the other options!
