B
Correct answer
Explanation
Genetics is the science of genes, heredity, and the variation of organisms. It studies how traits are passed from parents to offspring through DNA, the molecular structure of genes, mutations, and genetic variation within populations. The term derives from 'genesis' meaning origin or creation. Geology studies Earth's physical structure. Parentology and Hereditory are not legitimate scientific terms.
