What is the focus of chemistry?

  1. Biological functions

  2. Structures and properties of matter

The correct answer is: Structures and properties of matter

Chemistry is the study of the structures and properties of matter. It involves analyzing and understanding the composition, structure, and behavior of substances at the molecular and atomic level. Biological functions, historical artifacts, and geological formations are all topics in different fields of study and not the main focus of chemistry. Therefore, options A, C, and D are incorrect.
