The kind of CSS that requires a separate file is **external** CSS. This type of CSS is written in a separate file with a `.css` extension, and it is linked to an HTML document using a `<link>` tag in the `<head>` section of the HTML.

The other options you mentioned are:

- **Inline CSS**: This is CSS applied directly within an HTML element using the `style` attribute.
- **Internal CSS**: This is CSS written within a `<style>` tag in the `<head>` section of an HTML document.

So, the correct answer is **external** CSS.
