The answer IS D: 1. You can only call function of Smart Contract by referring its public address. If address is lost, this contract will remain existing orphan forever. 2. You must have specific "privilege" to access functions, some are only meant for contract owner. 3. You must have at least a certain amount of gas to perform transaction, in order to avoid DDoS and spam and wasteful calls.
