What is the output of this code?

object obj = 3.14;
if (obj is int n)
{
    Console.WriteLine($"Integer: {n}");
}
else
{
    Console.WriteLine("Not an integer");
}

ANot an integer

BCompilation error

CInteger: 3.14

DInteger: 3

Step-by-Step Solution

Solution:

Step 1: Understand the type of obj
obj holds a double value 3.14, not an int.
Step 2: Evaluate the if condition
The condition obj is int n is false because obj is not an int. So, the else block runs.
Final Answer:
Not an integer -> Option A
Quick Check:
Type mismatch leads to else = D [OK]

Quick Trick: Type must match exactly for 'is' pattern to succeed [OK]
