This would be called a D. Sinkhole. Sinkholes occur because groundwater washes and deteriorates at limestone under the surface. This leads to underground gaps. Once the pressure becomes high enough, the sinkhole collapse from gravity leaving a dent similar to potholes in the road.

The best answer in this case is C, "the researchers applied creativity to solve a problem in running an experiment".
Distributing the computing load across the global community by sharing processing power is a creative response to tackle the challenge in simulating protein folding for the experiment. This does not change or reduce the scientific merits of the experiment, so we can discount the first two answers (a & b). Answer d talks about well established scientific techniques, although the question wasn't really centered around the specific techniques, so it's not as relevant an answer as C.
Answer:
<u><em>Starfish</em></u> reproduce every winter by ejecting there eggs into the water, since they only live on average 35 years they reproduce about 35 times in their lifetime. Only a couple of the eggs will fertilize and turn into a Starfish.
<u><em>Hippos</em></u> are the only mammals in Africa that reproduce in water, Hippos reproduce in May and through June. Hippos usually live to around 40 to 50 years, and most hippos through May and June reproduce more than one time.
Explanation:
Hippos strategies of reproducing are better than Starfish.
