Select the C#.NET program that correctly prints Hello C#.NET to the console.

Difficulty: Easy

import System;\nnamespace CuriousTabConsoleApplication\n{\n class MyProgram\n {\n static void Main(string[] args)\n {\n Console.WriteLine('Hello C#.NET');\n }\n }\n}
using System;\nnamespace CuriousTabConsoleApplication\n{\n class MyProgram\n {\n static void Main(string[] args)\n {\n WriteLine('Hello C#.NET');\n }\n }\n}
using System.Console;\nnamespace CuriousTabConsoleApplication\n{\n class MyProgram\n {\n static void Main(string[] args)\n {\n WriteLine('Hello C#.NET');\n }\n }\n}
using System;\nnamespace CuriousTabConsoleApplication\n{\n class MyProgram\n {\n static void Main(string[] args)\n {\n Console.WriteLine('Hello C#.NET');\n }\n }\n}
using static System.Console;\nnamespace CuriousTabConsoleApplication\n{\n class MyProgram\n {\n static void Main(string[] args)\n {\n Console.WriteLine('Hello C#.NET');\n }\n }\n}

Correct Answer: using System;\nnamespace CuriousTabConsoleApplication\n{\n class MyProgram\n {\n static void Main(string[] args)\n {\n Console.WriteLine('Hello C#.NET');\n }\n }\n}

Explanation:

Introduction / Context:
This checks familiarity with basic program structure, namespaces, and how to call static methods such as Console.WriteLine in C#.

Given Data / Assumptions:

A minimal console app uses using System; and Console.WriteLine.
Keywords and directives must be valid in C# (e.g., C# uses using, not Java’s import).

Concept / Approach:
Validate syntax elements: the correct namespace import, the presence of a Main method, and correct qualification of Console.WriteLine or a valid using approach.

Step-by-Step Solution:

Option A uses 'import' (invalid in C#) → reject.Option B lacks qualification of WriteLine and does not use using static → reject.Option C uses 'using System.Console;' which is invalid; correct is 'using static System.Console;' in newer C# or write Console.WriteLine → reject.Option D has correct using directive and fully qualified Console.WriteLine → accept.Option E mixes using static with Console.WriteLine call; though legal with using static, it still compiles, but the prompt asks for a standard correct example; D is the canonical solution.

Verification / Alternative check:
Compile Option D; it prints exactly the required text.

Why Other Options Are Wrong:
A uses a non-C# directive; B and C misuse WriteLine/using; E is acceptable in newer C# but deviates from the most basic canonical pattern expected here.

Common Pitfalls:
Confusing Java and C# syntax or misusing using static.

Final Answer:
using System; … Console.WriteLine('Hello C#.NET');
