The sign test is a non-parametric test that compares two dependent samples to determine if there is a significant difference between them. It is based on the number of positive and negative differences between the pairs of observations. If the null hypothesis is true, then the probability of a positive difference is equal to the probability of a negative difference, which is 0.50. Therefore, the answer is A.
