The correct answer is D) Both A and C.
If "the impious man is not he who denies the gods of the many, but he who attaches to the gods the beliefs of the many," then
"believers in personal immortality and divine providence are impious" and "believers in atomism are pious."
We are talking about a part of the text "Epicurus: the Extant Remains." In "Epicurus, Letter of Meneoceus," the second paragraph says "...For Gods there are, since the knowledge of them is by clear vision. But they are not such as the many believe them to be: for indeed they do not consistently represent them as they believe them to be. And the impious man is not he who denies the gods of the many, but he who attaches to the gods the beliefs of the many. For the statements of the many about the Gods are not conceptions derived from sensation, but false suppositions, according to which the greatest misfortunes befall the wicked and the greatest blessings the good by the gift of the Gods."
