B. the global sea surface temperature anomaly.
C. the number of hurricanes used in the study.
D. None of the answer options is correct.
answer : number of hurricanes above or below average ( A)
Explanation:
The response variable is number of hurricanes Above or below , because from the response it can be deduced that what causes the temperature of the sea to be above the average sea temperature is the number of Hurricanes above the average number of hurricanes per year. hence the response variable is (The number of hurricanes above or below per year )
