If you are asking which of the choices fits the description best, I would say the answer is probably sympatric speciation, assuming that the organisms occupy the same geographic area.
Sympatric speciation is the genetic divergence of multiple populations (from a single parent species/ancestry) inhabiting the same geographic region; such that those populations become different species or structurally diverse.

Do you know what any of those terms mean? try weeding out the terms which are obviously inappropriate and then start thinking about whether which of what's left would fit a situation where things that started out the same (same ancestry) now show differences (structural diversity). I'll give you a start - I doubt very much that 'sympatric speciation' is what's being looked for here.
