Final Answer :
A
Explanation :
The null hypothesis in experiments comparing two groups typically states that there is no difference between the groups. In this case, it would mean stating that there is no difference in flavor ratings between the Dominos and Round Table pizzas. Choice A, despite its complex notation, is the only option that implies equality (i.e., a difference of 0), which aligns with the concept of a null hypothesis stating no difference.
