Answer 1

The correct option is (c) One base class can be derived into other two derived classes or more

Best explanation: One base class can be derived into the other two derived classes or more. If only one class gets derived by only 2 other classes, it is also hierarchical inheritance, but it is not a mandatory condition, because any number of derived classes can be there.
