Evolution means that populations of organisms change over time.
Explanation:
Evolution refers to the phenomena by which a population develops new traits and becomes more and more fit to survive in a given environment.
Evolution can be studied in two different ways- as a pattern of evolutionary changes and as a process of evolution.
Study of Evolution help us to understand the history of life.
Evidences of evolution support the view that species evolved from common ancestors rather than created separately..
These evidences are contributions of various fields of biology and geology.
This can provide a direction to give the appropriate and best management to the patient. THis can enhance the quality of healthcare and reduced the erroneous work which can be dangerous or fatal to the patients. Provide access to care and contain the cost of health services. This can be achieve with the use of intuitive thinking, leadership and learning from previous experiences. This can be combined for an effective approach.

Good luck and hopefully this helped.
Answer
The correct option is primary structure.
Explantion
A protein is composed of polypeptide chain which are organized into different structure as explain below:
Primary structure
The primary structure of protein is composed of a single polypeptide chain in which amino acids are arranged in linear form. Only covalent bond (peptide bond) hold the structure.
Example
Insulin hormone
Secondary structure
In secondary structure a single polypeptide chain is arranged in beta pleated sheet or in helical form. hydrogen bond and covalent bond responsible for providing stability to structure.
Example
Myoglobin
Tertiary structure
In tertiary structure a single polypeptide chain is arranged in three dimension. covalent bond, hydrogen bond and disulfide linkage help in maintaning this structure.
Example
Secretory proteins.
Quaternary structure
It is composed of more than one polypeptide chain and arranged in three dimension forming a globular structure. covalent bond, hydrogen bond, disulfide linkage, hydrophobic and hydrophilic interaction help in maintaining this structure.
Example
Haemoglobin.
