What is the output of this code?

var numbers = new[] {1, 2, 3};
var result = from n in numbers select n * 2;
foreach(var r in result) Console.Write(r + " ");

A1 2 3

B3 4 5

C2 4 6

DSyntax error

Step-by-Step Solution

Solution:

Step 1: Understand the select projection
The query multiplies each number by 2, so 1 becomes 2, 2 becomes 4, 3 becomes 6.
Step 2: Trace the output loop
The foreach prints each doubled number followed by a space: "2 4 6 "
Final Answer:
2 4 6 -> Option C
Quick Check:
Select doubles numbers = 2 4 6 [OK]

Quick Trick: Select transforms each item; multiply 1,2,3 by 2 = 2,4,6 [OK]
