Answer:
2. <em>A reference of type A can be treated as a reference of type B</em> - False
Base class or its objects are not related to their derived class (or its objects).
Explanation:
class A {
int a;
public A() {
a = 7;
}
}
class B extends A {
int b;
public B() {
b = 8;
}
}
///////////////////////////////////////////////////////////////////////////////////////////////////////
1. <em>After the constructor for class B executes, the variable a will have the value 7 </em>- True.
When an object of a derived class is declared, the constructor of base class is called before the constructor of derived class (is called).
3. <em>Both variables a and b are instance variables </em>- True.
Classes can have instance, or member, variables and methods.
4.<em> After the constructor for class B executes, the variable b will have the value 8</em> - True.
When object of class B is declared, its constructor was called, which initialized variable b to 8.

You should really state what language you are using. I have produced your method in C#, and should be easily translatable in to any other language.
static void RotateRight<T>(T[] arr)
{
T temp = arr[arr.Length - 1];
for (int i = arr.Length - 1; i >= 0; i--)
{
if (i == 0)
arr[i] = temp;
else
arr[i] = arr[i - 1];
}
}
