Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use a single page to avoid scrolling.
Options D and E are correct. A single-page dashboard (D) allows users to see key information at a glance without scrolling, improving efficiency. A consistent color scheme (E) reduces cognitive load and makes the dashboard easier to interpret. Option A (3D charts) is discouraged because 3D effects can distort data perception and add visual clutter. Option B (pie charts) can be used for parts of a whole, but it is not a universal best practice; they become hard to compare with many categories. Option C (including every metric) leads to information overload and reduces the dashboard's effectiveness.
