Solution

The correct option is A 1
In gel electrophoresis, an electric field is applied to gel that makes the negatively charged DNA fragments to move through a matrix of gel and thereby allows sorting of these fragments according to their size. The larger the fragment is, the shortest distance will it cover. Likewise, the smaller the fragment is, the far it will go. In shown gel, fragment 1 covers minimum distance among all another fragment which means that it is the largest one.
Therefore, the correct answer is option A.
