Data Sufficiency

(1) the profit exceeded $2 million on sales of 200,000 units
(2) the profit exceeded $5 million on sales of 350,000 units

(1) For 200,000 units, the profit exceeded $2 million
So, for 380,000 units, the profit exceeded (380,000 * 2)/200,000 = $3.8 million, but it is not clear if the profit exceeded $4 million or not; NOT sufficient.

(2) For 350,000 units, the profit exceeded $5 million.
So, for 380,000 units, the profit exceeded (380,000 * 5)/350,000 = $5.4 million, which clearly means that the profit exceeded $4 million; SUFFICIENT.

The correct answer is B.
