What is the main advantage of using high-level programming languages?

High-level programming languages are designed to be more user-friendly and accessible, which significantly enhances the ease with which humans can read and write code. This user-friendly nature is achieved through abstractions that allow programmers to use vocabulary and structures that are more aligned with natural language and problem-solving concepts, rather than the complex and intricate details of machine code.

By providing constructs that are intuitively understood, high-level languages simplify the process of coding, allowing developers to focus on solving problems rather than getting bogged down in the mechanics of the underlying hardware. This enables greater productivity, enhances collaboration among developers, and reduces the likelihood of errors, making programming a more efficient and error-resistant endeavor.

In contrast, options related to direct execution by hardware or machine code proximity pertain to low-level programming languages, which are designed for performance and efficiency but can be more challenging for humans to use. Additionally, while higher-level languages do support certain memory management features, this is not their primary advantage; rather, this aspect varies widely among different languages and is not a definitive trait of high-level programming as a whole.
