Final Answer :
A
Explanation :
Flood basalts eruptions are associated with mass extinctions in the fossil record. These massive volcanic events have historically led to significant environmental changes, including rapid increases in atmospheric CO2, acid rain, and global cooling or warming, which in turn have contributed to widespread species die-offs.
