These come together in decision support systems:

• A. Data and information
• B. Data and knowledge
• C. Knowledge and wisdom
• D. Information and knowledge

Answer: (D)

In decision support systems, guidance comes from combining information with knowledge. Data are the raw facts; when those facts are organized and given context, they become information. Knowledge arises when you apply models, rules, and experience to that information, turning it into actionable understanding. A DSS uses information to present the situation clearly and uses knowledge to interpret options, apply rules, and forecast outcomes. This pairing lets the system suggest meaningful trade-offs, forecasts, and recommended actions rather than just listing data. Data alone lacks interpretation, while knowledge without context lacks the specific situational information; wisdom represents higher-level judgment beyond routine decision support. Therefore, information and knowledge work together to drive effective decision support.
