What is the overlap of Data Set 1 and Data Set 2?
A. high
B. moderate
C. low
D. none

Answer: C
Step-by-step explanation:
It's definitely a low data overlap. Out of 9 samples for both, 2 match - leading to an approximately 22% share in data. It's not medium because there's not a solid amount of matching data, and its not 'none' because there is matching data.
