Solution

The correct options are
C Life originated from inanimate objects.
D It was proposed by Urey and Miller.
The theory of abiogenesis or biochemical evolution states that complex organic molecules like ammonia and nitrogen ringed structures were formed from simpler chemical substances like methane, hydrogen and nitrogen. From here, these complex organic molecules evolved through their interaction with each other and the environment, and started forming even more complex structures and molecules, eventually forming the first instance of a molecule of life, the RNA.​ It was proposed by Oparin and Haldane in the 1920s and later experimentally proved by Urey and Miller around 1953.
