How is a person regarded as stupid commonly referred to?

The term "dolt" specifically denotes a person who is perceived as lacking intelligence or understanding. It originates from old English and has been used historically in derogatory contexts to describe someone who is slow-witted or foolish. This term can imply a certain level of social disapproval, highlighting a failure to grasp concepts or perform tasks that may be considered basic or fundamental.

While all the choices reflect derogatory terms for someone regarded as lacking intelligence, "dolt" stands out because of its historical connotation and frequent usage in literature to illustrate a person's dullness or ineptitude. This gives it a specific flavor that relates closely to a lack of cognitive ability, unlike other terms that may have broader meanings or connotations.
