Best answer
The correct option is (d) Both Aggregation an Association

The explanation is: In both Aggregations and Association of objects of related classes can occur independently. For example, an employee can have a bank and a bank can have an employee. Also, Association is a superset of Aggregation, therefore, it also follows the same.
