The answer is option C. Number of double covalent bonds between carbon atoms is responsible for causing different shapes of saturated and unsaturated fatty acids. The double covalent bond causes kink in the unsaturated fatty acids because of which their stacking is disrupted and they become loosely packed. The problem with double covalent bond is that unlike single covalent bond it can't rotate and has almost cis-configuration. This is also the reason behind their liquidity at room temperature.

The correct answer is option (A) the fossil record.
Coordinated stasis refers to the stasis or the no evolutionary changes in the organisms for millions of years, which is followed by extinction and formation of the new species.
Fossil records have the evidence of ecological and evolutionary stability in the species over a long period of geological time scale separated by intervals of abrupt change. The best example of this being the animals of the Middle Devonian Hamilton group. Thus, fossil record is the only source of record showing this long period of stasis and separated by periods of abrupt changes in the species due to environmental pressures.
