Answer:
B. Feelings of joy after acting unethically may be a motivation factor in cheating, stealing, deception, etc.
Explanation:
'Is There a 'Cheater's High'?' is an article written by Romeo Vitelli, Ph.D. In his article he tries to examine the fact what makes people, like Frank Abagnale, cheat without feelings of remorse or guilt about the act.
The central idea that the author develops throughout the text is that new research of the 'cheater's high' suggests that people can actually feel positive after committing unethical acts instead of guilt/shame/remorse as previously studied. According to researcher Nicole Ruedy, emotions are vital in acting ethically or unethically.
Thus the correct statement that develops the central idea of the text is option B.
