All of the options mentioned are valid reasons for using source code in programming. However, the primary reason for using source code is that it is easier for humans to understand and write. Source code is written in programming languages that are designed to be readable and expressive for human programmers. It allows programmers to write instructions and algorithms in a way that is easier to comprehend, maintain, and debug. While it's true that computers ultimately need machine code to understand and execute instructions, source code serves as an intermediary layer between human programmers and the machine. Additionally, well-written source code can also enhance security by making it harder for hackers to decipher and exploit vulnerabilities.
