Proof of Stake (PoS) consensus is most often needed for and implemented by public blockchains. Public blockchains require a consensus mechanism that is energy-efficient and scalable, and PoS addresses these needs by reducing energy consumption compared to Proof of Work (PoW). PoS also enhances security and decentralization, making it a suitable choice for public blockchains where large numbers of participants contribute to block validation.
Answer should be D. https://ethereum.org/en/developers/docs/consensus-mechanisms/pos/ The keys when we opt for PoS from PoW, it is because of having better energy efficiency and stronger immunity to centralization. Protecting wealth and asset is NOT the particular reason why it assists, if PoW is considered perfect.
