Answer: B

Explanation:

A compiler is a specialized program that converts the entire source code written in a high-level programming language into machine code, which can be executed by the computer's CPU. This translation process is essential because computers cannot directly understand high-level programming languages; they can only process machine language. The compilation process includes syntax analysis, optimization, and code generation, which results in a standalone executable file. By compiling code into machine language, the compiler allows for efficient program execution and enables developers to use high-level languages to write applications that run on different hardware platforms.
