Answer:

a.DNA

Explanation:

• when there was very primitive condition in the early earth...billion years ago..the reductant atmosphere and the gases like methane, nitrogen forms the frame work elements...C,H,O,N..

•then these further as time passes forms the cabohydrates...amino acids...nitrogenous compound. .which soon started to become more complex

•further time masses now the compounds gets to form something living . ...something which is replicable..something which reproduce...this is basis of nucleic acid....from where our progenate or primitive life forms arise

•and this nucleic acid in the form of stable DNA..gets evolved and the immense biodiversity in earth is the result of this organic evolution..

so life in varied forms conneted by the single genetic material..

  1. RNA cannot be stable compound as compared to the dna ...its not forms the initial basis
  2. wbcs and RBcs are the blood cells in the plasma of body ...they are crucial...but not form...constituents of living organisms..

hope it helps..

good luck
