Every installation of WordPress has a default theme.

• A. Custom theme
• B. Default theme
• C. Child theme
• D. Minimal theme

Answer: (B)

WordPress always comes with a theme that is bundled with the core software, called the default theme. This theme is included in every WordPress package so there’s a ready-made design you can use right away or switch to as a starting point. It serves as a baseline for development and ensures you have a working presentation layer even before you customize anything. A custom theme is one you build or install yourself, not something that ships with WordPress by default. A child theme is a separate theme that inherits from another theme to extend or modify it, not the one that comes bundled by default. A minimal theme isn’t a standard built-in option in WordPress. So the default theme is the correct idea because it’s the theme that is packaged with WordPress itself.
