The correct answer is:

C. The result from part​ b, since it is the probability of the given or more extreme result.

Explanation: When determining whether a particular result is significantly high (in this case, 6 girls in 8 births), we typically look at the probability of obtaining that result or a more extreme one. In probability theory, for a result to be "significantly high," the probability of that result or a higher one must be relatively small.

Part b likely represents the probability of getting 6 or more girls (the given result or more extreme), which is essential for making this determination. Hence, part b is relevant.
