b. Association
c. Aggregation
d. Composition

Answer 1

Association

Answer 2

Option(b) Association is the relationship that exists between the two classes student and hostel.

• How two classes are connected can be identified by looking into their relationship.
• When some properties of one class are taken by another class then that type of relationship is termed inheritance.
• But in aggregation relation no dependencies are there, any update on one class will not affect the other class.
• In the composition there is thick bonding between the two classes, one can not stand without the other class.
• The relationship that exists between individuals and an organization can be represented using association relations, as this type of relation shows the connection between the two and how they make use of each other.
