The correct answer is D.
From the scientific research conducted so far, we know that in the early Earth's history the atmosphere lacked oxygen and was mostly filled with other gases like methane. The increase in oxygen levels happened when the plants started producing oxygen as a byproduct of the process of photosynthesis.
The research so far also shows that the RNA was present before the DNA and that the microspheres might have been essential to the development of life on Earth.
Carbohydrates
Carbohydrates are polymers of carbon, hydrogen and oxygen. They can be classified as monosaccharides, disaccharides and polysaccharides. Carbohydrates are found in starch, fruits, vegetables, milk and sugars. They are an important source of a healthy diet.
Nucleic Acids
The nucleic acids include DNA and RNA that are the polymers of nucleotides. Nucleotides comprise a pentose group, a phosphate group, and a nitrogenous base group. All the hereditary information is stored in the DNA. The DNA synthesised into RNA and proteins.
Proteins
Proteins are the polymers of amino acids. These include the carboxylic and the amino group. There would be no lipids or carbohydrates without proteins because the enzymes used for their synthesis are proteins themselves.
Lipids
Lipids are a hydrophobic set of macromolecules, i.e., they do not dissolve in water. These involve triglycerides, carotenoids, phospholipids, and steroids. They help in the formation of the cell membrane, formation of hormones and in the and as stored fuel.

Answer:
was introduced during the Renaissance
Explanation:
A correct flow chart is DNA i.e., gene (transcription) >> mRNA + tRNAs (translation) >> amino acids or protein >> phenotype. It is the flow of the genetic information.
<h3>What is the flow of genetic information?</h3>
The flow of genetic information refers to the molecular process from DNA to the final phenotype (i.e., protein product).
During gene transcription, a particular fragment of DNA called gene is used as a template to generate an mRNA.
Subsequently, the mRNA serves as a template to generate a linear chain of amino acids, i.e., a protein, by a process called translation.
The final protein can be considered as the phenotype (in this case, the albinism trait) because it is the observable feature.
