Answer: C
Such a hypothesis is a null hypothesis.
A null hypothesis states that there is no difference between groups, situations or outcomes, or no relationship between variables. The study then tests whether the data allow it to be rejected.
An alternative hypothesis is the opposite: it states that a difference or relationship does exist. A hypothesis of association states that two variables are related, and a hypothesis of difference states that groups differ. Both assert something, so neither is the 'no difference' hypothesis.
