A method is distinguished from a function by its association with an object within object-oriented programming. Specifically, a method is defined within a class and operates on instances of that class, meaning it can access and modify the object's properties and utilize its context. This encapsulation of behavior and data is a core principle of object-oriented programming, incorporating information and behavior in a unified structure.

In contrast, a function typically exists as a standalone block of code and does not have inherent access to the data or state of an object unless explicitly passed as arguments. Functions are often more generalized and can be called independently of any object, emphasizing their utility across different programming paradigms.

The other options do not accurately capture the essential distinction: the notion that a method returns a value while a function does not is misleading, as both can return values based on their definitions. Additionally, the statement that a method is always quicker than a function is not necessarily true, as performance can depend on various factors such as implementation and context. Lastly, claiming there is no difference between the two fails to recognize the fundamental differences in their roles and usage in programming languages.
