The point (TB5971_11, TB5971_00) corresponds to the intersection of the contour lines that pass through the values of 30 and 40. Thus, the value of the function at this point is approximately halfway between 30 and 40, which is 35. The answer choice that is closest to 35 is B, which corresponds to a hexadecimal number that starts with 11eaa3e5_54ed.
