In Nature, Predator-Prey Cycles Can Continue for Many Years

In nature, predator-prey cycles can continue for many years.In laboratory cultures, both populations quickly die off unless new individuals are periodically introduced (i.e., immigration occurs) .Based on this information, cycles in nature might be maintained by any of these factors (or some combination of them) except

A) strong predation resulting in rapid evolution of prey defenses.
B) pockets of prey that survive and are able to rebuild the population.
C) continuous immigration of both predator and prey to maintain populations.
D) inherent stability exerting control from within the predator-prey interaction.
E) habitat and species complexity preventing complete elimination of predator or prey.
