Final answer:
Analytical chemistry involves the study of material composition. It includes separation, identification, and quantification of chemical components in matter. The correct answer to the given question is option A.
Step-by-step explanation:
Analytical chemistry is the study of the composition of matter, focusing on the separation, identification, and quantification of chemicals in samples of matter. Analytical chemists may use advanced instruments to analyze unknown materials to determine their components. It is one of the five main disciplines in chemistry, alongside physical chemistry, organic chemistry, inorganic chemistry, and biochemistry.
The correct definition of Analytical chemistry is: The study of the separation, identification, and quantification of the chemical components of natural and artificial materials. Hence, the answer to the student's question, among the given options, is A.
