Answer:
The answer should be "computer repair business"
Step-by-step explanation:
This is because as the question says this this person is trained as a computer support specialist, that means this is an expert in giving maintenance to computers and devices.
Rather than the other three options, they have a different purpose:
- IT project management consultant = It is in charge of giving solutions and maintaining networks and systems on a company
- Database design contractor = It designs and normalizes databases, as well as their management and maintenance in the near future.
- cybersecurity manager = It is responsible for the security of all systems and networks of the company, as well as finding important issues related to security within the informatic systems
