}a. Region of code within which variable value is valid and hence can be accessed.
b. No, relation with region where variable is declared its value is valid in entire scope.

}1. Memory allocated to ‘Value type’ is from heap and reference type is from ‘System. ValueType’
2. Memory allocated to ‘Value type’ is from ‘System. ValueType’ and reference type is from ‘Heap’
3. Structures, enumerated types derived from ‘System. ValueType’ are created on stack, hence known as ValueType and all ‘classes’ are reference type because values are stored on heap
public static void Main(string[] args)
{
int i = 123;
object o = i;
i = 456;
System. Console. WriteLine("The value-type value = {0}", i);
System. Console. WriteLine("The object-type value = {0}", o);
Console. ReadLine();
}public static void Main(string[] args)
{
int i = 546;
object o = i;
int n =(int) o;
o = 70;
System. Console. WriteLine("The value-type value = {0}", n);
System. Console. WriteLine("The object-type value = {0}", o);
Console. ReadLine();
