How does paine's use of hypophora advance his point that history is against the idea of hereditary kingship?

a. it leads him to state three ways the earliest kings rose to power, none of which are hereditary.
b. it allows him to provide factual evidence that could not have been presented otherwise.
c. it shows that he is an expert authority on the origin of monarchy.
d. it asks a question whose answer is obvious, and so it makes readers believe him.
(will up vote the correct answer! and hurry! ^^)
passage:
yet i should be glad to ask how they suppose kings came at first? the question admits but of three answers, viz. either by lot, by election, or by usurpation. if the first king was taken by lot, it establishes a precedent for the next, which excludes hereditary succession. saul was by lot, yet the succession was not hereditary, neither does it appear from that transaction there was any intention it ever should. if the first king of any country was by election, that likewise establishes a precedent for the next; for to say, that the right of all future generations is taken away, by the act of the first electors, in their choice not only of a king, but of a family of kings for ever, hath no parrallel in or out of scripture but the doctrine of original sin, which supposes the free will of all men lost in adam; and from such comparison, and it will admit of no other, hereditary succession can derive no glory. for as in adam all sinned, and as in the first electors all men obeyed; as in the one all mankind were subjected to satan, and in the other to sovereignty; as our innocence was lost in the first, and our authority in the last; and as both disable us from reassuming some former state and privilege, it unanswerably follows that original sin and hereditary succession are parellels. dishonorable rank! inglorious connexion! yet the most subtile sophist cannot produce a juster simile.

as to usurpation, no man will be so hardy as to defend it; and that william the conqueror was an usurper is a fact not to be contradicted. the plain truth is, that the antiquity of english monarchy will not bear looking into.

but it is not so much the absurdity as the evil of hereditary succession which concerns mankind. did it ensure a race of good and wise men it would have the seal of divine authority, but as it opens a door to the foolish, the wicked, and the improper, it hath in it the nature of oppression. men who look upon themselves born to reign, and others to obey, soon grow insolent; selected from the rest of mankind their minds are early poisoned by importance; and the world they act in differs so materially from the world at large, that they have but little opportunity of knowing its true interests, and when they succeed to the government are frequently the most ignorant and unfit of any throughout the dominions.
