Another Bitcoin/Blockchain question!

point Bitcoin mining is nown as protokowcase in order to create a valid Sock the mineras enticant amount of computational work to figure out on the ocendo be proposes adequate which of the following IS NOT on toidud proof of the bioci? To randomly se des points the computing power To make mining that have incentrate To mais foraminant Toow nodes to come for the right to the 1. Bitcoin mining is also known as proof-of-work (POW) because in order to create a valid block, the miner has to spent a significant amount of computational work to figure out a nonce, so that the hash of the nonce and the block to be proposed is adequately small. Which of the following is NOT a reason to include proof-of-work in the designs of permissionless blockchains? A. To randomly select nodes in proportion to their computing powers B. To make mining so costly that miners have incentives to not create invalid blocks C. To make it impossible for one miner to act like many different miners D To allow nodes to compete for the right to create blocks
