Bytecode can still be exploited, so that's not true.

Wait, are they really that secure? I've heard otherwise.

Yeah, they can be deterministic, but not always secure!

I disagree, flaws can take time to fix, not always quick.

Smart contracts are Turing complete, that's a big deal!

I recall that bytecode can be exploited, so I don't think option B is true. It seems too absolute.

I practiced a similar question about smart contracts, and I think they can be updated if flaws are found, but I'm not confident about option C.

I'm not entirely sure, but I feel like option A could be misleading since security can vary across different networks.

I remember discussing how smart contracts are Turing complete, so I think option D might be the right answer.

I'm pretty confident that the correct answer is A and E - using Exadata storage realms with the ASM-scoped security mode, as well as the database-scoped security mode.

I'm a bit confused about the conditions after the recovery. I'll need to carefully read through the options and think through the implications of each one.

Hmm, I'm a bit unsure about the differences between these methods. I'll need to think carefully about the definitions and characteristics of each one.

Hmm, this looks like a tricky one. I'll need to carefully read through the options and think about what I know about Worker Queues.

Option D is the clear winner here. Ethereum smart contracts are designed to be powerful yet predictable. That's what makes them so useful!

Haha, I guess option A is like saying 'bulletproof vests provide added security over not wearing any armor at all'.

I'd be wary of C - while updates are possible, it's not always 'quick' or straightforward to redeploy a smart contract with fixes.

B is a bit misleading - just because they're compiled into bytecode doesn't mean they can't be used unintentionally. We've seen plenty of smart contract bugs in the past.
