Incomplete question prevents definitive analysis Steps:

• The query cuts off after "Which statement", omitting whether it asks for the true, false, or best description.
• Review choices: A miscalculates average rate at $20,000 (27.5%, not 35%).
• B incorrectly limits "direct tax" to incomes above $10,000; the entire income tax is direct.
• C misapplies "proportional" (average rate rises from 27.5% to 31.25% between $20,000–$40,000).
• D claims regressivity at the $10,000 threshold, but average rate stays ~20% then rises (progressive, not regressive where average falls).

Not enough information.

Final answer: Not enough information.
