The answer is the third one (or C): their observable characteristics.

Explanation for each option: a) Their genes - Incorrect. This option refers to the genotype, which is the genetic makeup of an individual. b) A hereditary disease - Incorrect. While a hereditary disease can be part of an individual's phenotype, it is not the complete definition. The phenotype encompasses all observable characteristics, not just diseases. c) Their observable characteristics - Correct. The phenotype includes all the observable traits of an individual, such as height, eye color, and behavior, which result from the interaction of their genotype with the environment. d) Their chromosomes - Incorrect. Chromosomes are structures within cells that contain DNA. They are part of the genotype, not the phenotype.

Summary: The phenotype of an individual refers to their observable characteristics, which result from the interaction of their genetic makeup (genotype) with the environment.
