In the first section of the code, the portion before the underscore, all numbers and letters remain the same as the code in question. In the second section, the portion between the underscores, the first three characters (2cf) remain the same throughout all three codes. In the third section, the portion between the underscores, the first four characters remain the same (96cc) throughout all three codes. Finally, in the fourth section, the portion after the underscore, the code TBX8650_11 remains the same throughout all three codes.

The only difference between the original code and the second code is in the third section, where one character changes from 0 to 1. Therefore, the value of the code increases by the hexadecimal value of one, which is 4, in the third section.

In the third code, the value of the code changes from 0 to d, indicating an increase of 13 in the hexadecimal system. However, the question asks for the increase if the value in the third section was increased by 1. Therefore, we only need to consider the increase of 1 in the third section, which would result in an increase of 1 in the overall value of the code.

Therefore, the difference between the original code and the third code is an increase of 4.4 (the increase of 4 in the third section and the increase of 0.4 in the last section due to the change in the code). The answer is B.
