The correct option is D Either, or
Correlative conjunctions are pairs of conjunctions that work together. Some examples are either/or, neither/nor, and not only/but also. The given sentence requires the use of correlative conjunctions.Either/or - are used together to offer a choice between two things. In the given sentence one has to choose between going to the market or taking rest during the Saturday evening. Thus Option D is correct. The combination both/and indicates that the two items are equally presented and included. Hence Option B is incorrect. Option A can be ruled out as 'either'' is not followed by 'nor' but by 'or'.While 'either' is used to offer a choice between two things,'nor' is used before the second or further of two or more alternatives (the first being introduced by a negative such as ‘neither’ or ‘not’) to indicate that they are each untrue or each do not happen. When though is used with a verb in the subjunctive mood (expressing doubt, a condition contrary-to-fact, a wish, a concession) is followed by yet. Though means ‘in spite of something’ and thus Option C is incorrect.
