Option A is the way to go. Who needs true randomness when you've got the block timestamp? It's like rolling dice, but with extra steps!

I'm going with option C. The RANDAO smart contract is designed specifically for this purpose, so it must be the best choice.

I think option B sounds like a good idea. The block hash is always different, so it should work, right? Blockchain magic, baby!

Option D is the correct answer. The Ethereum blockchain is a deterministic environment, so it's not possible to truly generate a random number.
