Final answer:
Feudal IT governance is represented by individuals or groups of IT executives managing their IT resources independently, in contrast to a monopoly, where a central body controls IT resources. So, the correct answer is option a.
Step-by-step explanation:
The IT governance archetype that consists of individuals or groups of IT executives is categorized as feudal. In the feudal model of IT governance, different business units within an organization have their own IT strategies and systems, which are managed by the unit's respective IT leaders.
This can create a dispersed and decentralized approach to IT governance, where each "feudal lord" has control over the IT resources within their "fiefdom". This is in contrast to the monopoly model, where a single central body has control over all IT resources, similar to how a company with a monopoly has control over a particular market.
So, the correct answer is option a.
