Final answer:
Unfortunately, without the specific figure, it's impossible to determine which statement is true regarding the origination and extinction rates from stage a to d. The question appears to be related to speciation and extinction rates in a biological context.
Step-by-step explanation:
To accurately address the student's question, it is essential to have access to 'the figure above' pertaining to the statement choices provided. However, using the reference information provided, we can infer that the question likely pertains to topics of speciation, extinction rates, and potential effects of human population on biodiversity in an ecological context.
For example, speciation is indeed the process of creating new species as described in D of the provided reference. Moreover, the calculation method for extinction rates (as in b of the reference) involving a large number of observations and measurements might not account for unobserved extinctions, indicating that extinction rates could be underestimated, as stated in d of the reaference.
