A network for distributing information is any system or arrangement that moves data, files, or resources from one point to another, whether between computers, through email servers, or by sharing a single output device.
Cloud storage distributes files across the internet to be accessed from multiple locations, several computers connected to one printer distribute print jobs to a shared device, and e-mail distributes messages between users across a network. All three genuinely move or share information between separate points.
Microsoft Word does not fit this description: it is a word-processing application used to create and edit documents on a single computer. It does not, by itself, move or share information between different computers or devices, which is why it is the one item that is not a network for distributing information.
When a question asks which item does not belong, check each item against the defining feature stated in the question, here, distribution of information between points, rather than just recognising the terms as computing-related.
