Final Answer :
A
Explanation :
To determine the variability of a set of scores, we look at how spread out the scores are. A set with a greater range of scores (the difference between the highest and lowest scores) has greater variability. Set A has the greatest range (19-7=12) compared to sets B, C, and D. Therefore, set A has the greatest variability.
