To maximize the combined scores, we need to choose the subjects that give the highest total score for 3 hours of study time. We can calculate the total score for each possible combination of study hours as follows:

0 hours of economics + 3 hours of accounting = 50 + 70 + 70 = 190
1 hour of economics + 2 hours of accounting = 80 + 70 + 70 = 220
2 hours of economics + 1 hour of accounting = 90 + 65 + 50 = 205
3 hours of economics + 0 hours of accounting = 95 + 65 + 50 = 210

Thus, the best combination is studying 2 hours of economics and 1 hour of accounting, which gives a total score of 205. Therefore, the answer is B.
