Explanation

Methods in JavaScript objects are functions attached to an object that perform actions or operations - for example, car.start() or user.login() - making B correct. They define behavior, not storage.

• A is wrong because storing data is the role of properties (e.g., obj.name = "Alice"), not methods.
• C is wrong because linking to web pages is the job of HTML anchor tags (<a href="...">), unrelated to JS object methods.
• D is wrong because structuring HTML documents is what HTML elements and the DOM do, not JavaScript object methods.

Memory tip: Think of an object as a person - properties are who they are (name, age), and methods are what they do (walk, talk). "Methods = actions" maps directly to the object-oriented concept of behavior.
