The correct answer is A. Prognostic framing
Explanation:
In sociology, social movements are commonly defined by three types of frames that are related to the perspective of individuals in relation to social and movements and reality. These frames include diagnostic framing in a problem or aspect to be changed is clear and has only one clear solution for individuals; prognostic framing in which the problem is stated along with a solution although there are more solutions considered by individuals and motivational framing in which the problem is directly linked to an action that needs to be carried out.
In the case individuals that are part of a movement claim there are different ways to solve a problem that is climate change which makes this frame different from diagnostic framing, but they propose one main solution that is outlawing privately owned cars and this does not directly call to action as in motivational framing and therefore "outlawing cars" is part of prognostic framing as options are considered and a solution is proposed without a direct action.
