Superglobals in PHP are accessed just like any other variable, but they are always available, no matter where you are in the script, even within ______.

The correct option is 2. Superglobals in PHP, such as $_POST or $_GET, are accessed just like any other variable. You can use them within functions, loops, classes, or conditional statements without the need for any special syntax or declarations. Superglobals are always available in all scopes, meaning you can access them from anywhere within your PHP script, regardless of where you are in the script's execution flow. This makes them convenient for accessing data from different parts of the script without having to pass variables explicitly.
