Final answer:
Having a small number of project team members is unlikely to increase project risk, while the other options can introduce additional complexities and challenges that increase the risk. Therefore correct option is A
Step-by-step explanation:
Out of the options provided, a small number of project team members is the choice that is least likely to increase the level of project risk. Having a small number of team members can promote effective communication, coordination, and decision-making, leading to reduced risks in the project.
On the other hand, the remaining options, such as a project involving new technology, a lack of technical expertise within the information systems staff, and a project that impacts many parts of the organization, can all introduce additional complexities and challenges that increase the project risk.
