I’m leaning towards 51%. Seems too low though.

Group consensus usually requires a supermajority, so C is right.

Definitely not 100%, that's unrealistic.

Haha, A) 52%? What is this, a presidential election? Blockchain needs a stronger consensus than that!

B) 74% is an interesting choice, but I'm going with C) 75%. It's the classic threshold for these kinds of decisions.

E) 100%? Really? That's just impractical. Who wants a blockchain where everyone has to agree on everything?

D) 51% seems too low for a group consensus. Blockchain is all about security, so the threshold should be higher.

I vaguely remember that 74% is often used in some contexts, but it seems a bit odd compared to the usual percentages.

I’m a bit confused; I thought it was either 51% or 100%, but now I can't recall which one is correct.

I remember the professor talking about this in class. I believe the correct answer is 75% consensus. Time to put my blockchain knowledge to the test!

Wait, I thought group consensus required a higher threshold than just a simple majority. Let me think this through again - I want to make sure I get the right answer.

Okay, I've got this. For group consensus, the majority of members need to agree, so the answer is 51%. Easy!

Hmm, I know group consensus is important for blockchain security, but I'm not confident I can recall the exact percentage required. I'll have to review my notes and try to reason through the options.
