Grace Hopper is famous for what contribution?

• A. Devised the first commercial electronic computer
• B. Created the first graphical user interface
• C. Invented email
• D. Wrote the first antivirus software

Answer: (B)

The main idea here is recognizing Grace Hopper’s impact on making programming more accessible through high-level languages and the compiler. Hopper helped develop the first compiler and played a key role in creating COBOL, a business-oriented language designed to be readable and closer to everyday language. This allowed programmers to write instructions in a form that humans can understand, while the compiler translates those instructions into machine code that computers can execute. COBOL became widely used for business systems, government record-keeping, and data processing, which is why Hopper is celebrated as a founding figure in software development. The other options point to innovations in other areas (such as interfaces, messaging, or security tools) that aren’t what Hopper is known for. The best answer emphasizes her work in language design and compilation, not graphical interfaces, email, or antivirus software.
