What does Solidity compile into upon processing?

Text file and executable file
Source code and ABI
Byte code and ABI
JavaScript and byte code

The correct answer is: Byte code and ABI

Solidity, which is the primary programming language for writing smart contracts on the Ethereum blockchain, compiles into two key components: bytecode and the Application Binary Interface (ABI). The bytecode is the low-level code that the Ethereum Virtual Machine (EVM) understands and executes. It is the actual instruction set that will be deployed to the blockchain when the smart contract is created. This bytecode is what gets stored on the blockchain and is essential for the smart contract to function within the Ethereum ecosystem. The ABI, on the other hand, is a critical aspect as it defines how the smart contract interacts with the outside world, including how functions can be called and how data structures are formatted. It serves as a communication interface between the contract and other programs, such as user interfaces or other contracts. Thus, the correct choice highlights both of the vital components produced during the compilation process of Solidity, making it clear why bytecode and ABI are essential outputs of this process.
