Answer:
Mitochondria stops working.
Explanation:
When the mitochondria of fish exposed to Rotenone, it inhibits the cellular respiration which is the main cause of death of fishes. This inhibiting of cellular respiration in mitochondria leads to reduction in cellular uptake of oxygen and this reduction is responsible for the death of fishes. This Rotenone releases by the plants present in the water as well as used as pesticides for killing of fishes.
Oxygen is a small molecule and it's nonpolar, so it easily passes through a cell membrane. Carbon dioxide, the byproduct of cell respiration, is small enough to readily diffuse out of a cell. Small uncharged lipid molecules can pass through the lipid innards of the membrane.
The answer for this question is "founding population arrives, biogeographic isolation occurs, genetic changes occur, reproductive isolation results" so it is letter A
