Answer 1

The correct option is B 1 $\to$ b; 2 $\to$ c; 3 $\to$ d; 4 $\to$ a

Theory of chemical evolution was proposed by Oparin and Haldane. The assumptions of this theory are that earth's atmosphere was radically different from today's conditions, primitive earth's atmosphere did not have oxygen, life arose from chemical reactions where solar radiation, UV rays and lightning must have been the chief sources of energy for these reactions.
Darwin proposed theory of natural selection which states that organisms which develop advantageous variations will be selected by nature while others which don't will not.
Lamarck proposed the theory of inheritance of acquired characters which states that organisms will pass on the characters that they develop in their lifetime to their next generation.
Hugo de Vries stated that variations are sudden heritable changes, also known as mutations (mutation theory).
