Which statement correctly describes a discount as a data concept?

• A. It adds a late fee to the total
• B. It is a promotion that applies to all data and not to individual rows
• C. It is only a credit after a lengthy audit
• D. Reduced price applied directly to a row; awards after the fact are credits

Answer: (D)

Discounts are price reductions that affect a specific item on a single line of the data. When a discount is applied, the amount shown on that row is reduced, so the total reflects the lower price right away. This per-line adjustment keeps revenue and pricing data accurate at the item level, which is how discounts are typically modeled in transactional data. The other descriptions describe scenarios that aren’t how discounts are usually represented: a late fee adds cost, a blanket promotion applies to all rows regardless of the item, and a post-audit credit is a separate adjustment after the fact. The best fit is a reduced price applied directly to a row, with any post-fact credits treated as separate adjustments rather than the discount itself.
