Answer:
to share information through e-mail messaging
to increase trafficking through their web sites
to facilitate the use of desktop virtualization
Explanation:
The organization employees can share the information via an email client like outlook express as well. However, if the email option is included within the web application then it will be a kind of expeditating communication or speed up communication, as the users can mail from within the web application itself. And the web application does serve as a website as well, and hence can help in increasing the trafficking. And since its a sort of SaaS, it does facilitate the use of desktop virtualization. However, the purpose of the web application can change only with the new version, or else it is not possible. And hence, the fourth option is not legitimate fully. And hence, the correct options are as mentioned above in the answer section.
