Q. Which best describes a 51% attack in blockchain?
#A
#B
#C
#D

A 51% attack happens when one miner/validator controls over half the network’s power or stake. This lets them rewrite history or double-spend coins, threatening security. It’s rare on large chains like Bitcoin but a risk for smaller ones.
