Answering the Question

The CSS selector that is denoted by a period (.) followed by a class name is known as the Class Selector.

Explanation

1. Class Selector: In CSS, when you prefix a class name with a period (.), it allows you to select all HTML elements that have that specific class attribute. For example:

   .myClass {
       color: blue;
   }
   

   This would apply the style (color: blue) to any HTML element that includes the class "myClass".

2. ID Selector: Denoted by a hash (#) followed by an ID name, it selects the element with that specific ID, and IDs should be unique within a page.

3. Element Selector: Targets HTML elements directly by their tag name (without any prefix).

4. Attribute Selector: Selects elements based on the presence or value of an attribute.

In summary, the correct answer is the Class Selector.
