What Explains the Error in the Given Code Segment?

Which of the following best explains why the code segment does not compile?

A) In line 1, m1 cannot be declared as type FamilyMembership and instantiated as a Membership object.
B) In line 2, m2 cannot be declared as type Membership and instantiated as an IndividualMembership object.
C) In line 3, m3 cannot be declared as type Membership and instantiated as a FamilyMembership object.
D) In line 4, m4 cannot be declared as type FamilyMembership and instantiated as a FamilyMembership object.
E) In line 5, m5 cannot be declared as type Membership and instantiated as a Membership object.

Answer:

The correct answer is A) In line 1, m1 cannot be declared as type FamilyMembership and instantiated as a Membership object.

This is because you cannot instantiate an object of a subclass with the type of its superclass. In line 1, m1 is declared as type FamilyMembership, but it is being instantiated as a Membership object.

Since Membership is the superclass of FamilyMembership, this instantiation is invalid and will result in a compilation error. The other lines do not have this issue, as they are all correctly instantiating objects with their respective types.

So the correct answer is A.
