D)A and B
E)All of the above

A founder event involves the establishment of a new population by a small subset of individuals from the original population. This subset may not represent the full range of genetic diversity present in the original population, leading to a decrease in genetic variation in the founder population (option A). Additionally, the random sampling of alleles from the original population during the establishment of the new population can result in changes in allele frequencies (option B). The coalescent process refers to the tracing of the ancestry of genes within a population, and is not directly related to founder events (option C). Therefore, the best choice is D, as both options A and B are valid explanations of how a founder event can change allele frequencies.
