The changes that take place in the DNA (deoxyribonucleic acid) molecule in relation to various environmental, chemical, and genetic factors leads to biodiversity.
Hence, the option (a) is incorrect.
The hierarchy of scale is arranged based on the complexity of cells. The order for the hierarchy of biological organization is arranged in the following manner from least complex to the most complex: molecule organelle cell tissue organ organ system organism population community ecosystem. Each level is more complex with reference to cellular complexities and is built on the basis of the previous level.
Hence, option (b) is incorrect.
Ecological roles of all living organisms are dependent of various factors and are not directly related to having DNA as the information molecule.
Hence, option (d) is incorrect.
All the living organisms utilize DNA molecule for storing and passing on the genetic information from one generation to another. This provides evidence of a shared common ancestor.
Hence, the correct option is (c) a shared common ancestor.
