The gain in consumer surplus is calculated as the area of the triangle formed by the price drop from $6 to $3. The base of the triangle is the quantity change from 0 to 190 units, and the height is the price change of $3. The area (consumer surplus gain) is 1/2 * base * height = 1/2 * 190 * 3 = $285. However, without the figure, this calculation assumes a linear demand curve and the quantities provided. Since the correct answer is not listed based on this calculation, and assuming a potential misunderstanding or miscommunication in the question or calculation process without the figure, the correct answer provided here might not match the expected outcome based on the figure not being visible.
