Concept:A biographical sketch is a short, factual overview of a person's life that highlights major events and achievements, unlike a full autobiography or a critical essay.
Explanation:- A biographical sketch provides a concise account of a person's life, focusing on important milestones and contributions. It serves as an introduction or summary, not an exhaustive narrative.
- Option B exactly matches this definition: "A brief account of a person's life, highlighting key events and achievements."
- Option A describes a fictional story, which is not factual. Option C is a critical analysis of flaws, not a sketch. Option D is a detailed autobiography written by the person themselves, which differs in length and perspective from a biographical sketch.
Answer:Option B (Option 2) is the correct answer.
