Explanation / Answer
The right answer is B
THe measure of the reliability that accompanies an inference separated the science of statistics from the art of fortune telling. A palm reader like a statistician may examine a sample ( hand) to make inference about the population (your future). But it does not include any measure on how true the palm reader's inference is.
Using statistical measure we can determine a bound on estimation error. This bound is simply a number that our estimation is unlikely to exceed.
Hence we can say that the inference is incomplete without a measure of the reliability.
