Which tool is a 32-bit assembler-level analyzing debugger for Windows and can attach to running programs and log arguments?

• A. Immunity Debugger
• B. OllyDbg
• C. WinDbg
• D. GDB

Answer: (B)

The capability being tested is using a Windows-focused, 32-bit debugger that works at the assembly level and can attach to running processes while showing what arguments are passed to functions. OllyDbg is a classic match: it’s a 32-bit Windows assembler-level debugger designed for dynamic analysis of binaries without source code. It lets you attach to a live process, step through instructions, inspect registers and memory, and crucially observe and log the arguments being passed as the program executes. This focus on disassembly-driven analysis and real-time argument visibility makes OllyDbg the best fit for this description. Immunity Debugger also targets Windows and supports attaching to processes and scripting, but its strength lies more in exploit development tooling and flexibility via Python. WinDbg is extremely powerful for Windows debugging and can attach to processes and log activity, but it’s a more heavyweight tool with a steeper learning curve and isn’t as tightly aligned with the classic assembly-level, quick-attach analysis workflow. GDB exists for Windows as well, but it’s not the typical choice for Windows-specific 32-bit assembly-level debugging and live argument logging.
