Answer: (B) Python
HTML (HyperText Markup Language) is the foundation for structuring web content. CSS (Cascading Style Sheets) is used for styling the visual presentation. JavaScript adds interactivity and dynamic behavior. XML (Extensible Markup Language) is used for storing and transporting data, but it's not a core language for front-end web development in the same way the others are. Python is a general-purpose programming language often used for back-end development, but not typically for directly building the user interface of a website.

Answer: (B) Bit
Bit (Binary Digit)
Bit is the smallest unit of data in a computer.
In bynary units of measurement - 4 Bit = 1 Nibble; 8 Bit = 1 Byte; 1024 Byte = 1 Kibibyte (KiB); 1024 Kibibyte = 1 Mebibyte (MiB); 1024 Mebibyte = Gibibyte (GiB); 1024 Gibibyte = 1 Tebibyte (TiB); 1024 Tebibyte = 1 Pebibyte (PiB); and so on.
In decimal units of measurement - 1000 Byte = 1 Kilobyte (KB); 1000 Kilobyte = 1 Megabyte (MB); 1000 Megabyte = Gigabyte (GB); 1000 Gigabyte = 1 Terabyte (TB); 1000 Terabyte = 1 Petabyte (PB); and so on.

While computers can process vast amounts of data and execute complex algorithms to simulate intelligence (Artificial Intelligence), they do not possess inherent intelligence, intuition, or the ability to think, reason, or make decisions based on emotion or consciousness like humans do. Their "intelligence" is derived from the programs and data they are fed.

HTML (HyperText Markup Language) is the fundamental language used to create the structure and content of a web page. While CSS is essential for styling and JavaScript adds interactivity, HTML is the core language that defines the basic building blocks of a website, such as headings, paragraphs, images, and links. Without HTML, you wouldn't have a web page to style or add interactivity to.
