Dear student

Please refer the solution below for the said query


The correct option is B.​

According to the Oparin and Haldane theory, the chemical evolution preceded organic evolution. The simple organic molecules (such as amino acids, simple sugars, fats, etc) originated from inorganic precursors such as C, H, N, O. These organic molecules combined to form large organic molecules (macromolecules) like proteins, nucleic acids etc. These macromolecules combined to form coacervates. Coacervates are spherical droplets surrounded by tight skin of water molecule. These coaservates became the possible precursors of cells.
