Which system helps predict the level of tax payable in different scenarios?

The correct answer is the Expert System. An Expert System is a type of artificial intelligence that uses a knowledge base and inference rules to simulate the decision-making ability of a human expert. In the context of predicting tax payable in various scenarios, an Expert System can analyze different variables and provide recommendations or insights based on predefined rules and parameters related to tax laws and regulations. It processes complex data and rules to produce reliable outputs regarding tax liabilities under various circumstances.

By leveraging established tax knowledge and applying it to different financial situations, the Expert System effectively assists users in understanding potential tax outcomes, thus making it a valuable tool for financial planning and decision-making related to taxation. This capability is particularly useful for individuals and organizations needing to navigate different tax strategies and liabilities.

In contrast, a Decision Support System primarily focuses on providing data-driven analysis for problem-solving and decision-making but may not necessarily possess the specialized tax knowledge that an Expert System does. An Executive Information System is designed to provide top management with easy access to internal and external information relevant to strategic decision-making, without being specifically geared towards tax predictions. A Resource Planning System typically integrates various business processes but does not specialize in tax calculations or the simulation of tax outcomes.
