Choice D is the best answer. In lines 1-9("To...solicitude"), Burke explains that people have "consecrated the state" to "avoid . . . the evils of inconstancy and versatility," and that people should examine "the faults of the state . . . with pious awe and trembling solitude." Burke then explains that society is taught to "look with horror on those children of their country who want to hack that aged parent in pieces" (lines 10-12,"By... in pieces"). Burke is arguing that children want to revise the state, or "this aged parent," by amending its faults. In this context, "state" refers to a political entity, or government, that attempts to protect its citizens from "the evils of inconstancy and versatility."
Choices A, B, and C are incorrect because in this context, "state" does not mean style of living, position in life, or temporary condition.
