C#.NET strings — evaluate the output of: String s1 = "ALL MEN ARE CREATED EQUAL"; String s2; s2 = s1.Substring(12, 3); Console.WriteLine(s2);

Introduction / Context:This tests correct use of Substring(startIndex, length) with zero-based indexing.

Given Data / Assumptions:

• s1 = "ALL MEN ARE CREATED EQUAL"
• startIndex = 12, length = 3

Concept / Approach:Substring takes characters starting at startIndex and returns exactly length characters. Indexes are zero-based and include spaces as characters.

Step-by-Step Solution:

Verification / Alternative check:Print s1[12], s1[13], s1[14] to confirm characters.

Why Other Options Are Wrong:ARE or REA correspond to other ranges; CREATED is too long.

Common Pitfalls:Off-by-one errors or forgetting spaces count toward indices.

Final Answer:CRE
