A) Yes: the relation is linear.
B) No: speeding is a categorical variable.
C) Yes: the two variables are quantitative.
D) No: the correlation does not imply causality.

Final Answer :
D
Explanation :
Correlation does not imply causality. A high correlation between the number of speeding tickets and the kilometers of well-paved roads does not necessarily mean that well-paved roads cause more speeding tickets; other factors could be at play.
