According to attribution theory, attributions vary along which of the following dimensions?

A) internal/external causes
B) known/unknown causes
C) regular/irregular causes
D) consistent/inconsistent causes

Attribution theory proposes that attributions can vary along the internal/external causes dimension, referring to whether the cause of behavior is attributed to personal factors (internal) or situational factors (external). Other dimensions mentioned in the options (known/unknown, regular/irregular, consistent/inconsistent) are not central to attribution theory.
