Can someone help me with this?

i believe the answer is A. what the question is saying is that the null hypothesis significant at alpha = .05 or at 95%, so the only logical answer would be A which is saying that the null hypothesis is also statistically significant at alpha = .1 or at 90% confidence. i hope this makes sense to you. .01 is saying there is a 99% confidence level which is not necessarily true from the information provided.
