Answer:
A. Reduce Risk
Explanation:
In Decision support system, Decision makers would heavily rely on data provided by technologies in order to make the final decision (like the scenario above).
This system tend to make the decision making process become simpler and efficient, but it does not reduce the risk that decision makers have to take since there are too many factors that can influence the outcome of the decision.
For example, in separating relevant and irrelevant information, sometimes emotions could be the most determinant factors that must be prioritized to separate the two. This type of emotion , wouldn't be able to be factored by data compiled by technologies alone.
