Why each option

Wireshark's 'File > Export Objects' feature allows analysts to reconstruct and save files transmitted over protocols such as HTTP, SMB, and DICOM from a captured TCP stream.

AFile > Export ObjectsCorrect

The 'File > Export Objects' menu in Wireshark provides the ability to extract and save files transferred within captured network streams, including HTTP, SMB, IMF, DICOM, and TFTP objects. This is the only built-in Wireshark feature that reassembles and exports application-layer objects from packet captures. It is commonly used by analysts to recover files transmitted over the network for further forensic analysis.

BAnalyze > Extract

There is no 'Analyze > Extract' menu option in Wireshark - the Analyze menu is used for display filters, expert info, and protocol decoding.

CTools > Export > TCP

There is no 'Tools > Export > TCP' menu path in Wireshark - the Tools menu provides options like Lua scripting and credential extraction, not file export.

DView > Extract

There is no 'View > Extract' menu option in Wireshark - the View menu controls display preferences such as columns, coloring rules, and packet layout.
