Which of the following expressions evaluates to false?

class c1 {}

class c2 extends c1 { }

class c3 extends c2 { }

class c4 extends c1 {}

c1 c1 = new c1();

c1 c2 = new c2();

c1 c3 = new c3();

c1 c4 = new c4();

c1 instanceof c1

c2 instanceof c1

c4 instanceof c2

c3 instanceof c1

If we analyze the given piece of code, C1, C2, C3 and C4 are 4 classes.

C1 is the base class and does not derive from any other class. C2 is a class which inherits C1. C3 is a class which inherits C2 and indirectly inherits from C1. C4 is a class which inherits C1 directly. If analyses the instance creation statement,

c1 instance of C1 is valid because the object is created for class C1.

c1 c2 = new C2() is valid once again the object is created for Class C2

c1 c3 = new C3() is invalid because the class C3 directly inherits from C2 and not from C1

c1 c4 = new C4() is valid
