Answer:

The correct option is B. If the hypothesis tracing the extinction of the dinosaurs to an impact is correct, the dinosaurs died off largely because of global climate effects initiated by dust and smoke that entered the atmosphere after the impact.

Explanation:

Scientists claim that the global temperature raised by 10 degrees, in the mid-Cretaceous period.

Two theories are made for this rise in temperature. According to one of the theory, scientist believe that  it happened due to an asteroid impact whereas the second theory depicts that it occurred due to volcano eruptions in various parts of the earth.

It is generally accepted today that the changes in climate due to asteroid impact became the reason for the extinction of dinosaurs.
