The correct answer is: D.Punctuated equilibrium.

Explanation:

The idea that the mass extinction of dinosaurs, caused by a sudden asteroid impact, led to rapid changes and the emergence of new species fits well with the concept of punctuated equilibrium. This theory suggests that evolution occurs in relatively brief, rapid bursts of change followed by long periods of stability (stasis). The asteroid impact could have triggered a rapid period of evolutionary change by creating environmental pressures that led to the emergence of new species.
