After increasing the size of the cafeteria, it was decided to add 3 more rows of tables and to increase the original number of tables in each row by 2. The maximum number of tables the cafeteria can hold is 126. If r represents the original number of rows the school administrators planned to have in the cafeteria, which of the following represents this situation?

A.
2r2 + 7r + 6 ≤ 126
B.
2r2 + 8r + 6 ≥ 126
C.
2r2 + 7r + 6 ≥ 126
D.
2r2 + 8r + 6 ≤ 126
