Answer:
A. Wiki
Step-by-step explanation:
Since the company wants to create knowledge storehouses that employees can edit as needed, adding contributions from their own personal experience or updating existing information, Wikipedia will be a very useful company for them.
Anyone with Internet access can write and make changes to Wikipedia articles, except in limited cases where editing is restricted to prevent disruption or vandalism. Users can contribute anonymously, under a pseudonym, or, if they choose to, with their real identity. The new employees always can have access to a good number of informations.
