Which of the following statements about CSS selectors is correct?

Class selectors can indeed be applied to multiple elements within a document, making them highly versatile and useful for styling multiple items simultaneously. When you define a class in your CSS, you can assign that class to any number of HTML elements, allowing for consistent styling across those elements without having to write repetitive styles for each one. This is particularly advantageous in web development, where maintaining clean and organized code is essential for both functionality and ease of updates.

On the other hand, ID selectors are unique and can be applied to only one element per page. Thus, while both class and ID selectors serve important purposes in CSS, the ability of class selectors to style multiple elements allows for greater flexibility and efficiency in managing CSS and HTML structure.
