Mnemonic-based approach:
Rogers and Shoemaker's model is widely remembered through the mnemonic SMCRE: Source, Message, Channel, Receiver, Effect. This mnemonic reflects the natural flow of any communication event, someone (Source) has something to say (Message), sends it through a medium (Channel) to someone else (Receiver), producing some outcome (Effect).
Reading the mnemonic letter by letter directly gives the sequence Source, Message, Channel, Receiver, Effect, which corresponds to (A), (B), (C), (D), (E).
Matching this against the options, only option (1) lists the elements in exactly this order, so option (1) is correct.
