If the observed frequencies do not equal the expected frequencies in each cell of a table for independence, it is most likely due to sampling error. This means that the sample taken may not be representative of the entire population, leading to a difference in the observed and expected frequencies. The other options (A, C, D) are not relevant to explaining the difference between observed and expected frequencies in a contingency table.
