Which tool is used to inspect the dependencies of an executable and understand library relationships?

• A. PE Explorer
• B. Dependency Walker
• C. BinText
• D. Strings

Answer: (B)

Understanding which libraries an executable relies on and how they connect is about mapping the DLLs an application imports and how those libraries relate to each other. Dependency Walker specializes in this: it analyzes the import and export tables of a PE file and builds a clear view of every module the program depends on, showing the dependency chain, the exact functions pulled from each library, and flags for missing or incompatible DLLs. This makes it the best fit for diagnosing runtime issues caused by absent or mismatched libraries and for grasping how the program links to external code.

Tools that focus on other aspects, like PE structure or resources, aren’t as directly aimed at presenting the whole dependency graph and load order. And utilities that pull out strings from binaries serve a different purpose, not mapping library relationships.
