Answer: Single covalent bond in the long hydrocarbon chain.
Saturated fatty acids are long chains of hydrocarbon ( with single covalent bond) ending with the carboxylic group (-COOH). This means those fatty acids which possess only single bonds in their chemical structure are called as saturated fatty acids. They are densely packed, which makes them solid at room temperature.
Example- Lauric acid ( present in coconut oil). It has 12 carbon atoms in its chemical structure.

D. the process by which species change as successful traits are passed on to the next generation
Explanation:
Natural selection is the differential survival and reproduction of individuals due to differences in phenotype. It is a key mechanism of evolution, the change in the heritable traits characteristic of a population over generations.
Carbon is most abundant in the <u>atmosphere</u> and <u>hydrosphere</u>.
Explanation:
In the atmosphere, carbon is mostly present in the gaseous state of carbon dioxide. Plants absorb atmospheric carbon through photosynthesis and prepare food which is used by other living organisms. Respiration by plants and animals returns carbon back to atmosphere.
Next to atmosphere, carbon is abundant in the hydrosphere dissolved in water. Aquatic plants and marine organisms absorb carbon dissolved in water to prepare food. This carbon is also used to produce shells and other marine structures.
Carbon is also present in lithosphere and biosphere.
