A series of studies by Catalino,Furr,and Bellis (2012) ,which tested the ideas behind self-presentation theory,suggested that social anxiety is,in fact,produced by

A) self-presentation motivation but not social self-efficacy
B) social self-efficacy but not self-presentation motivation
C) neither social self-efficacy, nor self-presentation motivation
D) both social self-efficacy and self-presentation motivation

The studies conducted by Catalino, Furr, and Bellis (2012) suggested that both social self-efficacy (the belief in one's ability to handle social situations) and self-presentation motivation (the desire to project a certain image to others) are factors that contribute to social anxiety. Therefore, the best choice is D, which states that both social self-efficacy and self-presentation motivation produce social anxiety.
