Either you return my books ____ pay their cost.

• A. Nor
• B. And
• C. Or
• D. But

Answer 1

The correct option is C 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 a correlative conjunction. The combination either/or indicates that there is a choice between the two choices, and only one can be selected. Either is always used with or and it is used to express alternatives and or a choice between two (and sometimes more) things. Thus Option C is correct.'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. It cannot be associated with 'either' which is used to choose between two alternatives. Thus Option A is ruled out.'.And' helps to add one clause or phrase to another similar one. since 'either' is used here it indicates that there is a choice between the two. Thus option B is discarded. The conjunction but is used to suggest a contrast but it cannot be used along with 'either'.Thus Option D can be ruled out.
