 Answer the question below. First, respond with the single best option letter (A, B, C, or D). Then provide a concise reasoning (1–3 sentences). Use both the retrieved evidence and your own medical knowledge to choose the most accurate answer. 

Question:
Recently two methods, CPAP conventional and bubble CPAP were compared, in the conventional method 90 out of 160 showed extubation failure while 40 out of 160 showed extubation failure in the bubble method. Which test would be the best to compare the statically significance between the rates of extubation in the two tests.? 

Options:
{'A': 'Paired test', 'B': 'Chi square test', 'C': 'Student test', 'D': 'ANOVA'}'
