In CSS, a rule is composed of a selector and a declaration block. The rule is the entire part that defines how styles should be applied to elements matching the selector.

CSS Rule Components:

Selector: Identifies the HTML elements to be styled (e.g., body, .name, #item).

Declaration Block: Contains one or more declarations, each consisting of a property and a value, enclosed in curly braces {}.

Example Analysis:

Option A:

body {

background-color: white;

}

This is the full rule, consisting of the selector body and the declaration block { background-color: white; }.

Option B:

background-color: white;

This is just a declaration, not a complete rule.

background-color: white,

This is an incorrect declaration due to the comma, and not a complete rule.

Option D:

color: black

This is just a declaration, not a complete rule.
