Answer:
The correct answer is option B. Posting files to a web-based shared site.
Explanation:
One of the biggest hurdle in collaborating is that the data is not shared efficiently. Both parties are not on the same page due to which they are unable to communicate and coordinate their productivity strategies effectively.
In order to keep both parties on the same page and updated, all the data files must be shared on an online web page from which they can view and hence stay updated.
It will give rise to healthy exchange of ideas and productive strategies.
