A security analyst is comparing two LLMs for threat intelligence summarization. Model A has 8K token context; Model B has 128K token context. For what specific security use case is Model B's context advantage most significant?

• A.Answering factual questions about known CVEs, where Model B has more training data
• B.Real-time phishing email classification where Model B is faster due to its larger context
• C.Training a custom security domain model, where Model B's context window accelerates fine-tuning
• D.Analyzing complete malware analysis reports or APT campaign reports that span hundreds of pages, where Model A would need to be called multiple times with chunked inputs (losing cross-document reasoning) while Model B can process the full document in a single call and reason holistically
