1- The correct answer is D. A personification is a literary device used to give a concept or an object the features of a person. In this case, the concept of Death is personified when the author refers to it as a "he" as well as when it performed an action, that is Death stopped someone. Tipically people are the ones who perform actions and can be refered to with personal pronouns. The adverb "kindly" also adds to the personification, and suports the idea of Death being polite.
2- The correct answer is D. Onmipotent has the meaningful of "all powerful", that is having more power than the rest. The last part of the excerpt helps give that idea, that God's omnipotent power is so vast that even if yours is greater than it is actually is, it would still not be enough.
