C) A population bottleneck occurred, altering the resulting allele frequencies.

Explanation:

Population bottleneck can be described as the reduction which occurs in a population due to any environmental factor like fire or due to the activities of humans like hunting etc.

A large number of Beatles got killed due to the fire. The reduced population that is left has an altered gene frequency. This phenomenon can be described as a genetic drift that has occurred and caused changes in the genetic frequencies.
