C . Groups of students who support bullying contribute to its development.

Explanation:

In the informational text Bullying in Early Adolescence, The Role of the Peer Group by Dorothy L. Espelage details how bullying may have begun. It also discusses in detail how this societal practice not only affect but also influence others to a certain extent.

The whole text delves into how this practice of bullying may not only be a simple case of "interaction between a bully and a victim". This aggressive "attack" at someone weaker not only affects the person but also may ruin his whole life. And bullying comprised not only of a physical attack at someone but also any form of "negative actions" which can also include ignoring someone. These factors all contribute to the effects of the misbehavior, which are all forms of bullying, one way or the other. The central point of the whole text can be that a group of people who support the bullying act also contribute to the development of such practices.

Thus, the correct answer is option C.
