Which debugger is described as a 32-bit Windows debugger ideal when source code is unavailable?

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

Answer: (A)

When you don’t have the source code, you rely on binary-level debugging to understand what a program does. OllyDbg is a 32-bit Windows debugger built specifically for that purpose. It excels at analyzing compiled binaries without symbols or sources, offering a strong disassembler, clear views of memory and registers, and flexible breakpoints so you can step through code, follow function calls, and observe how the program behaves in real time. You can also patch instructions in memory to test how changes affect execution, which is invaluable when source code isn’t available. Other tools can be powerful in their own right—WinDbg is highly capable for Windows-specific debugging and often relies on symbols; Immunity Debugger adds scripting capabilities; GDB is a staple for Unix-like environments and can be used on Windows but isn’t the native choice for straightforward 32-bit Windows binary analysis. OllyDbg’s focus on binary analysis without source makes it the best fit for the described scenario.
