C sounds fishy, how can it be independent from time zones?

A is totally wrong, miners can't just change the timestamp like that.

I'm a bit unsure about this one. I'll need to review the documentation on PCF manifest configuration to make sure I select the right solution.

I'm leaning towards change strategy as the input. Elicitation is often done to understand the impact of a proposed change, so having that context would be important.

Okay, I've got this. The key here is to use the right Replicat parameter to control error handling. I'm pretty sure option B, HANDLECOLLISION, is the way to go.

Hmm, the question mentions using a round-robin approach to load balance the APs. I wonder if that's the key to optimizing roaming.

I think we might need a security level to control access to the hidden issues, but I'm not completely sure how it works in this context.
