We need to look at the values with a stem of 2 (representing the 20s) and 3 (representing the 30s). For 20s, we have 26, 27, 29, and 29. For 30s, we have 30, 31, 31, 32, 33, 33, 34, and 34. Counting these values, we get 4+8=12 values that are at least 25 but less than 35. Therefore, the answer is Choice B) 12.
