Explanation

Option B is correct because correlation measures are most valid when the variables are normally distributed. Option A is incorrect since a correlation of -1 indicates a perfect negative relationship, not no relationship. Option C is false because correlation does not imply causation, and a correlation of +10 is not possible as correlation coefficients range from -1 to +1. Option D is unrelated to Galton's original findings. Option E is incorrect because correlation coefficients cannot exceed 1.
