You discover a narrow subterranean river in the outback of Australia and estimate that it is at least 50 million years old, traveling through caves undisturbed by humans. You gather a crew of scientists to perform species sampling of the river as well as metagenomics techniques to calculate microbial diversity. The results indicate that although short in length, the river is extremely diverse. You even get to name a new species of shrimp after yourself! During one of your many interviews, you are asked to explain the high diversity of the subterranean river. What hypothesis would you cite?

A. The species-productivity hypothesis.
B. The intermediate disturbance hypothesis.
C. The species-time hypothesis.
D. The species-area hypothesis.
