Which type of argument is perceived as most credible

A)  one-sided argument
B)  emotion-calming argument 
C)  two-sided argument
D)  fear-arousing argument

Studies have shown that a well-presented two-sided argument which acknowledges and addresses counterarguments is perceived as more credible than a one-sided argument. Fear-arousing arguments may be effective in certain situations but can also backfire and cause people to shut down or tune out. Emotion-calming arguments may be viewed positively but may not necessarily increase credibility.
