The answer is A , i know but can anyone explain me how and why?
Can anyone tell me how to interpret the confidence interval, especially can anyone explain the relationship between confidence interval and p value.

Waiting to someone to help me,
Tiya

the answer is A. the question ask about significance. For 95%confidence interval its p value should be less than 0.05.
