The main function of an assembly language is to provide a human-readable version of machine language. Assembly language is a low-level programming language that closely reflects the architecture and instruction set of a computer's hardware. It uses mnemonics and symbolic representations to represent machine instructions, allowing programmers to write code that is easier to understand and manage compared to binary or hexadecimal machine code.

Because assembly language is designed to be more comprehensible than raw machine language, it maintains a one-to-one correspondence with the machine-level instructions, making it much simpler for programmers to handle operations that directly manipulate hardware. This allows for greater control over system resources and hardware-level operations, which is crucial in systems programming, embedded systems, and real-time processing scenarios.

Other options fall short in their relevance to assembly language. While high-level programming languages usually abstract hardware details to allow for more complex programming without worrying about machine instructions directly, assembly language specifically aims to bridge the gap between high-level languages and machine code. The function of translating high-level languages directly into machine code is typically performed by compilers, not assembly languages themselves. Additionally, creating graphical user interfaces is not a function of assembly language; that task is generally handled by higher-level programming languages.
