Which statement correctly lists the minimum dimensions for a sump?

• A. Top 18 inches, Bottom 16 inches, Depth 24 inches
• B. Top 14 inches, Bottom 12 inches, Depth 20 inches
• C. Top 20 inches, Bottom 18 inches, Depth 26 inches
• D. Top 16 inches, Bottom 14 inches, Depth 22 inches

Answer: (D)

Focusing on minimum dimensions means identifying the smallest values that still meet the required standard for every dimension. The required minimums are a top opening of 16 inches, a bottom width of 14 inches, and a depth of 22 inches. The only option that uses exactly these smallest values for all three measurements is the one with Top 16 inches, Bottom 14 inches, and Depth 22 inches. Any option with a larger measurement describes a sump bigger than necessary (still acceptable, but not the minimum), and any option with a smaller measurement would fail to meet the minimum. So the exact minimum configuration is the correct choice.
