Concept:Ecopsychology examines the human need for contact with nature and its effect on psychological well-being.
Explanation:The passage presents ecopsychology as a field that links mental health to nature.
It identifies Theodore Roszak as an important leader in this field.
A study from Pennsylvania is used as supporting evidence.
That study found that patients recovered better when their rooms overlooked gardens rather than a parking lot.
This shows the positive role of nature in the healing process.
The correct keyword set must focus on the main thinker, the study location, and the central finding.
Option A names Wilson but does not match the passage’s specific ecopsychology evidence.
Option B offers very general terms such as urban dwellers and ecologists.
Option D includes human need but misses Roszak and the recovery study.
Option C correctly combines Roszak, Pennsylvania, and nature-induced recovery of patients.
Thus, option C is the most relevant and accurate set of keywords.
Answer:Option C
