• D
  91% (20)

Explanation

Debug provides the most detailed APM logging because it captures granular, low-level information about application internals - variable states, function calls, execution flow - everything needed to trace exactly what the application is doing at any given moment.

The distractors represent progressively less detailed levels: Error (A) only captures failures and exceptions, the least verbose level. Warning (B) adds potential issues that haven't failed yet, but still omits routine operational data. Informational (C) logs general milestones and normal operations, giving a high-level picture without the fine-grained detail needed for deep diagnostics.

Memory tip: Think of log levels as a funnel - Debug is the widest, catching everything, while Error is the narrowest, catching only critical failures. The order from least to most detail is: Error → Warning → Informational → Debug (you can remember it as "EWID" - Everything Will Include Debug).
