- Choose the correct statement among the following?
- Consider a class maths and we had a property called as sum.b is a reference to a maths object and we want the statement b.sum = 10 to fail.Which of the following is the correct solution to ensure this functionality?
- Consider a class maths and we had a property called as sum.b which is the reference to a maths object and we want the statement Console.WriteLine(b.sum)to fail.Which among the following is the correct solution to ensure this functionality?
- Which of these keywords are used for the block to handle the exceptions generated by try block?

A.
A property can be a static member whereas an indexer is always an instance member
|
|
B.
A get accessor of a property corresponds to a method with no parameters whereas get accessor of an indexer corresponds to a method with the same formal parameters lists as the indexer
|
|
C.
It is an error for indexer to declare a local variable with the same name as indexer parameters
|

D.
All of the mentioned
