B,C
Since we have a list of “Cycle”, anything at it’s hierarchical level or below it qualifies as addable to the list. So anything that implements it as an interface, or extends it through inheritance.
BUT NOT ANYTHING ABOVE IT! Adding “new Object()” to the list would call in the compiler to reject you in life as did your father.
b and c
B, C. Both statements confirms that MotorCycle is inheriting from the Cycle (whether is it an interface or an abstract class). The important point to remember here is that the myList is an ArrayList that includes objects of type Cycle (ArrayList). Accordingly, we can add any object of type Cycle or any subclass that inherits from it.
