When workers do not find their assignments challenging, they become bored and, therefore, achieve less then their potential. On the other hand, when works find their assignments too difficult, they give up and so again achieve less than what they are capable of achieving. It is, therefore, clear that no worker’s full potential will even be realized. Which one of the following is an error of reasoning contained in the argument?
A Mistakenly equating what is actual and what is actual and what is merely possible.
B Assuming without warrant that a situation allows only two possibilities.
C Relying on subjective rather than objective evidence.
D Confusing the coincidence of two events with a causal relation between the two.
