Answer:

The answer to this question is given below in the explanation section

Explanation:

The correct answer to this question is: it used a more English-like syntax.

The software developer use high-level language to develop or author the program because it is more likely to English syntax and it would be easy for a software developer to author a program easily instead of using low level language and remembering ones and zeros.

Other options are not correct because:

It can be used on computers without microprocessors: Each computer has a microprocessor either you develop a program using high-level or low-level languages. Changes and modifications are easy in high-level language than in low-level languages. so, the option that prevents anyone from making changes to the software later is wrong.  However, high-level languages are less complicated in learning and in authoring the programs but it does not use zeros and ones, it uses English-like syntax. So, the last option is also wrong.
