Solution
The correct option is D Watson and Crick
Watson and Crick first proposed the DNA model. Watson and Crick showed that each strand of the DNA molecule was a template for the other. During cell division, the two strands separate and on each strand a new "other half" is built, just like the one before. This way DNA can reproduce itself without changing its structure except for occasional errors, or mutations. The structure so perfectly fit the experimental data that it was almost immediately accepted.
So, the correct answer is option D.
