(2) The profit exceeded $5 million on sales of 350,000 units.

Statement 1: The profit exceeded $2 million on sales of 200,000 units.
The increase is not proportional. So, the information provided cannot be used to evaluate the profit on 380,000 units. Hence, statement 1 is NOT SUFFICIENT.


Statement 2: The profit exceeded $5 million on sales of 350,000 units.
Despite the fact that 350,000 units are less than 380,000 units, a profit of $5 million which is greater than the $4 million benchmarks has been generated. So, by the time 380,000 units will be sold, the total profit will definitely exceed $4 million. Based on this, statement 2 is SUFFICIENT.

Since only statement 2 is SUFFICIENT, the correct answer, therefore, is option B.
