C) reject the research hypothesis
D) ignore the null hypothesis

Final Answer :
B
Explanation :
The result "p < 0.05" indicates that the probability of obtaining these results due to chance is less than 5%. This means that there is a significant difference between the two groups being compared. Therefore, we reject the null hypothesis and conclude that there is evidence to support the research hypothesis.
