    Explanation

    High-level programming languages are designed to be easy for humans to read and write, using English-like words, commands, and syntax such as if, while, print, and return. These languages allow programmers to write code without dealing directly with the binary digits (0s and 1s) used by computers. The code is later translated into machine language by a compiler or interpreter so that the computer can execute it. Options A, C, and D are incorrect because high-level code itself is not written in machine language or binary; it is only converted into machine language after it is written.
