Back up or something in detail.

Back up or something in detail.

• A. Explain
• B. Describe
• C. Support
• D. Infer

Answer: (C)

Backing up a claim in writing means offering evidence and details that strengthen what you're saying. The best fit here is to support because it captures the idea of providing reasons, facts, examples, or quotes that bolster your main point. Explaining focuses on making the idea clear, which helps understanding but doesn’t by itself supply proof. Describing is about detailing what something is like, not proving a claim. Inferring is about drawing a conclusion from clues, not providing direct evidence. So providing support with specific information and evidence is what makes a claim convincing, which is why that option is correct.
