object val = 456;
string str = val as string;
Console.WriteLine(str == null ? "No string" : str);

B456

CException thrown

Dnull

Step-by-Step Solution

Solution:

Step 1: Use of as operator
The as operator tries to cast val (which is an int boxed as object) to string. This cast fails and returns null.
Step 2: Evaluate the conditional expression
Since str is null, the ternary operator prints "No string".
Final Answer:
No string -> Option A
Quick Check:
Failed 'as' cast returns null, not exception [OK]
