    I'm pretty sure it's either A or B.

    Well C and D say an increase in population, and the graph obviously shows that at point Z, the population decreased. So it can't be C or D.

    Possibility of B... due to sudden change in atmosphere effects the growth of the species and sudden drop occurs.

    @abb0t Do you agree that it is B?

    What is the difference between A and B?

    I think it's A. Since C and D both say an increase, which it obviously can't be, right?

    You see a decrease, but then you gradually see an increase. Mass extinction would not explain why there was an increase in the species.

    Dinosaurs, would be an example of a mass extinction.

    Ohh ok so then it has to be A right?
