Selected Answer: B
The Ethereum Virtual Machine (EVM) is indeed sandboxed, meaning it runs in a secure and isolated environment. This sandboxing is intentional to enhance security and prevent malicious actions. The EVM is designed to execute smart contracts within the Ethereum network, and it does not have direct access to external systems or hardware layers to maintain security and prevent potential vulnerabilities.
