The study of properties and methods of biological systems found in nature and the application of this knowledge in the design and improvement of artificial systems is known as:

(A) Bionics

Explanation:

Bionics: Bionics is an interdisciplinary field that combines biology and engineering. It involves studying natural systems to understand their design and functionality and then applying this knowledge to create or improve artificial systems. The goal is to develop technologies inspired by nature. For example, designing a robot based on the principles observed in animal locomotion or creating materials inspired by the structure of biological tissues.

The other options:

Bionomics: This term is more commonly associated with the ecological study of organisms and their relationships with each other and their environment.

Bionomy: This term is not commonly used, and its meaning can vary in different contexts.

Biometry: Biometry usually refers to the statistical analysis of biological data.

Therefore, the correct answer is (A) Bionics.
