The correct answer is C. Taking public transportation can benefit a person financially, create new social connections, and reduce stress.
Step-by-step explanation:
In an essay a thesis statement is the main claim that guides the essay in this statement the author of the essay show its position in relation to some topic or issue, this implies a thesis statement should state only one position related to one issue and it should be clear, precise and explicit. In the case of "Taking public transportation can benefit a person financially, create new social connections, and reduce stress" the author does not only state he/ she believes public transportation can benefit people but provides the way in which people can benefit (financially, create new social connections and reduce stress), additionally the words and word order used makes the position clear and easy to understand and avoids the use of extra words which make it concise. Thus, the thesis statement "Taking public transportation can benefit a person financially, create new social connections, and reduce stress" is the strongest one as it does not only claim public transport is beneficial but states the way in which it is beneficial, also it is concise but clear and states only one position, which makes it the most complete, believable and thus strongest thesis.
