If the function is called as a method of an object, `this` refers to that object. For example, if you have an object with a method and you call that method, `this` inside the function will point to that object. This behavior allows functions to access and manipulate the properties of the object that invoked them.

The concept differs when considering how `this` operates within arrow functions. Arrow functions do not have their own `this` context; instead, they inherit it from the surrounding (lexical) context. However, in the case of regular functions, understanding that `this` refers to the object invoking the function is crucial. In some contexts, particularly when using event listeners or when functions are passed as callbacks, `this` may not refer to the object you expect unless you bind it correctly.

The other interpretations provided by the choices may lead to misunderstandings about `this` in JavaScript. Though in some cases, `this` can reference the global
