Explanation
The ideas about evolution presented by Lamarck are known as Lamarckism. Lamarck's explanation of revolution revolved around two basic assumptions. The first one is the use and disuse of organs. Lamarck's second assumption is the inheritance of acquired characteristics. All three conditions were explained by Lamarck. Hence, D is the correct option.

About Evolution
Evolution describes heritable change in populations over generations through variation, natural selection and adaptation. Lamarckism explains inheritance of acquired characteristics, while Darwinism explains selection of favourable inherited variations; these historical explanations must not be confused with the modern genetic account of evolutionary change.
