Which of the following is a programming language?

Both C and Perl are recognized as programming languages, which makes the choice of both correct.

C is a general-purpose, high-level programming language that is widely used for system and application software development. It provides low-level access to memory and gives developers fine control over system resources, which enhances its efficiency and performance in various applications.

Perl, on the other hand, is also a high-level programming language, known for its text-processing capabilities and flexibility. It is often utilized in web development, system administration, and network programming. Perl’s syntax allows for rapid development and prototyping, contributing to its popularity for various scripting tasks.

In contrast, HTML, while essential for web development and the structure of web pages, is not classified as a programming language. It is a markup language used to create the layout and formatting of documents on the web. Thus, selecting both C and Perl highlights an understanding of programming languages and their roles in software development.
