Given below are four statements pertaining to separation of \(DNA\) fragments using gel electrophoresis. Identify the incorrect statements \((a)\; DNA\) is negatively charged molecule and so it is loaded on gel towards the Anode terminal \((b) \;DNA\) fragments travel along the surface of the gel whose concentration does not affect movement of \(DNA.\) \((c)\) Smaller the size of \(DNA\) fragment larger is the distance it travels through it. \((d)\) Pure \(DNA\) can be visualized directly by exposing UV radiation. Choose correct answer from the options given below

1. A \((a), (c)\) and \((d)\)
2. B \((a), (b)\) and \((c)\)
3. C \((b), (c)\) and \((d)\)
4. D \((a), (b)\) and \((d)\)
