L-dopa is effective against Parkinson's, but its enantiomer D-dopa is not. An enantiomers drug may not be equally effective. The enantiomer, in chemistry, is one of two stereoisomers that are mirror images of each other that are non-superposable, much as one's left and right hands are the same except for being reversed along one axis.

b. fundamental attribution error
Explanation:
In psychology, the fundamental attribution error refers to the tendency that we have to explain someone else's behavior based on internal factors (like their personality) and underestimating the influence of external factors on their behavior.
On the other way, we do the opposite when it comes to our own behavior, we tend to overemphasize the influence of situational factors when explaining our behavior and we underestimate the role our personality plays.
Therefore, the tendency to overemphasize the importance of personality factors when explaining someone else's behaviors while overemphasizing situational factors when explaining your own behaviors, is called the fundamental attribution error.
