Composition is the correct answer because it describes the relationship between objects where the parts cannot exist without the whole. In other words, the whole object owns the parts and if the whole object is destroyed or deleted, the parts are also destroyed or deleted. This is different from aggregation, where the parts can exist independently of the whole object. Polymorphism and Method are not related to this concept.
