Explanation

Executable files (.exe) are one of the most common vectors for malware delivery, so virtually all modern email security systems and spam filters automatically quarantine or block messages containing .exe attachments - this is standard policy, not a coincidence. Option A is wrong because internal corporate email systems don't routinely block messages between offices; that would break normal business communication. Option B is unlikely because the filter specifically flagged the attachment type, not its size, and size limits would typically bounce the message back with an error rather than silently route it to spam. Option D is implausible because file name length restrictions are not a real-world email filtering mechanism - no standard spam policy filters on how long a file name is.

Memory tip: Think "EXE = Execute = Executable = Possible malware." Spam filters are trained to treat .exe files as suspicious by default because they can run arbitrary code on the recipient's machine - unlike .pdf or .docx files, an .exe requires no additional application to cause harm once opened.
