The null hypothesis states that there is no difference between men and women in their attitudes toward marriage. This is the most appropriate choice as it directly tests the researcher's prediction that there will be differences between men and women. The other choices (A, B, and D) make specific predictions about the direction of the difference, which may or may not be supported by the data. The null hypothesis, in contrast, is a neutral statement that can only be rejected or fail to be rejected based on the evidence.
