Choice D is the best answer. In lines 25-29("because...perfection"), Burke describes the contract between a person and society as one that is "not a partnership in things subservient only to the gross animal existence of a temporary and perishable nature. It is a partnership in all science; a partnership in all art; a partnership in every virtue, and in all perfection." Describing that contract as a partnership in all things indicates its seriousness, while describing it as not being a "temporary and perishable nature" implies its permanence.
Choice A is incorrect because line 27("of a ...nature.") states that the contract between a person and society is not "temporary or perishable," meaning it is not brief. Choices B and C are incorrect because the passage does not compare the contracts in terms of complexity or precision.
