The null hypothesis is always a statement of no relationship or no difference. Therefore, option A is the correct choice as it states that there is no relationship between social activity and education. Options B, C, and D are not correct as they are not statements of no relationship or no difference. Option B suggests a zero correlation, option C suggests a positive correlation, and option D suggests an equality of means, but none of these statements are appropriate for the null hypothesis.
