In which situation is online collaboration most effective?

Correct answer: Members work in a shared document according to assigned roles

The governing concept is collaborative ICT use: people work toward a common outcome by sharing information, coordinating responsibilities, and contributing to a common workspace. A shared document with assigned roles makes contributions visible, reduces duplicate work, and supports editing from different locations. Separate unshared files are not coordinated, one-person work is not collaboration, and publishing a password creates a security risk. Thus, option B is correct.
