The correct response is:
A low-level programming language is designed for the computer to process. A high-level programming language is designed for the user(s) to understand.
This accurately captures the primary purposes of low-level and high-level programming languages. Low-level languages (such as assembly language) are closer to machine code and provide more control over hardware, while high-level languages (like Python, Java, or C++) are more user-friendly and abstract away many of the complexities of hardware management, making them easier for humans to read and write.
