Where will be a 'is a ' relationship will occur select one?
A. interface Person
class Employee implements Person
B. interface Shape
interface Rectangle extends Shape
C. interface Component
class Objects implement Component
{Component [] Component;}
Ans:B
I think A is also right,isn't it?

You are right!

So, if "class A extends B implements C" then we say that A "is a" B and A "is a" C also?
