A) Brooke's findings are relevant but insignificant.

Reason: The comparison to the known average ($97,000) is relevant to her question, but with only n = 3 (and no information on variability) she cannot reliably show the $130,000 mean is statistically significant — the result could easily be due to sampling variability or outliers.
