Answer: C. Unix shell
Explanation
Unix shells provide high-level command languages that automate complex operating system tasks efficiently. Such scripting environments qualify as fourth-generation languages due to their declarative command structures. Users accomplish substantial procedural work with concise statements characteristic of fourth-generation tools. Fourth-generation languages are designed to reduce programming effort compared to third-generation languages. They often feature database query tools, report generators, and operating system command shells. High-level abstractions allow users to specify what needs to be done without detailing every step.
System administrators use Unix shells to automate routine backups and server maintenance scripts. High-level scripting accelerates administrative task execution across modern computing environments. Understanding programming generation levels helps developers select appropriate tools for specific automation needs. Fortran is a classic third-generation programming language primarily used for numerical computations. Cobol is a third-generation language designed for business data processing and administrative systems. C plus plus is an object-oriented third-generation language offering low-level memory manipulation features.
