Consider the following class definitions.

publ ic class A

$\{$

publ ic St r ing message$($ int i $)$

$\{$

return $"$A$"+$ i ;

$\}$

$\}$

publ ic class B extends A

$\{$

publ ic St r ing message$($ int i $)$

$\{$

return $"$B$"+$ i ;

$\}$

$\}$

The following code segment appears in a class other than A or B$.$

A obj$1=$ new B$()$ ; $//$ Line $1$

B obj$2=$ new B$()$ ; $//$ Line $2$

System.out $.$pr int ln$($obj$1.$message$(3))$ ; $//$ Line $3$

System.out $.$pr int ln$($obj$2.$message$(2))$ ; $//$ Line $4$

Which of the following best explains the difference, if any, in the behavior of the code segment that will result

from removing the message method from class A $?$

$($A$)$ The statement in line $3$ will cause a compiler error because the message method for obj$1$ cannot

be found.

$($B$)$ The statement in line $4$ will cause a compiler error because the message method for obj$2$ cannot

be found.

$($C$)$ As a result of the method call in line $3,$ the message method in class B will be executed instead of

the message method in class A$.$

$($D$)$ As a result of the method call in line $4,$ the message method in class B will be executed instead of

the message method in class A$.$

$($E$)$ The behavior of the code segment will remain unchanged
