Wait, is the block difficulty affected by the 'tie' between blocks? I didn't realize Ethereum had a romantic side to it. Guess I better brush up on my Ethereum knowledge!

Ah, the old 'time between blocks' trick. I'm going to go with option C - it seems to match the information provided in the question better.

Relying on an Ethereum Committee to determine the block difficulty every two weeks seems a bit centralized. I wonder if that's really how it works in Ethereum.

The block difficulty increasing when the time between blocks is below 10 seconds and decreasing when it's above 20 seconds sounds like a reasonable way to adjust the difficulty. I'm curious to see if this is the correct answer.

That makes sense, it ensures the network maintains a consistent block time.

I believe option A is correct, as the block difficulty increases when the time is below 10 seconds.

I think the block difficulty in Ethereum is determined by the time between mined blocks.
