Which method is commonly used to access elements in the DOM?

The method to access elements in the Document Object Model (DOM) is commonly done using getElementById(). This function is integral to JavaScript and allows developers to retrieve a specific element by its unique ID attribute. Since IDs are meant to be unique within a page, this method provides a direct and efficient way to reference and manipulate single elements.

When using getElementById(), you provide the ID as a string argument, and the method returns the element corresponding to that ID, allowing for immediate access for further operations, such as changing styles, content, or attributes. This approach is foundational in interacting with the DOM and forms a key part of dynamic web development.

The other options listed, while they may sound plausible, do not represent standard methods for DOM access in JavaScript. Hence, getElementById() is the fundamental and most widely recognized method for this purpose.
