The given first statement indicates that clusters possess the tendency to reproduce by the process of fragmentation. Thus, it supports the hypothesis that the clusters possess the tendency to evolve. The second statement indicates that clusters are more fit, therefore, it also supports the hypothesis.
The third statement is contrary to the hypothesis. Therefore, it does not support the hypothesis. The fourth statement is in contrast to fitness, more abundancy shows more fitness. Therefore, it also does not support the hypothesis. Hence, the correct statements are a and b.
