The correct answer is: D. spot decision.
A spot decision is a decision that must be made quickly and without much time for deliberation. It is often made in response to a crisis or unexpected event. Spot decisions are often made by individuals or small groups, and they are typically based on limited information.
A group decision is a decision that is made by a group of people. Group decisions can be made in a variety of ways, but they typically involve some form of discussion and debate. Group decisions can be more time-consuming than individual decisions, but they can also be more effective, as they can benefit from the input of multiple people.
A major decision is a decision that has a significant impact on an individual or organization. Major decisions are often made after careful consideration and planning. They can be difficult to make, but they are often necessary to achieve long-term goals.
A minor decision is a decision that has a relatively small impact on an individual or organization. Minor decisions are often made quickly and without much thought. They can be relatively easy to make, but they can also be important, as they can add up over time.
In the context of the question, a crisis decision is a type of spot decision. It is a decision that must be made quickly and without much time for deliberation, often in response to a crisis or unexpected event.
