The answer to that question would c because a is a past tense word and d is not the correct grammar at all
Both bc they all follow each other so it really depends on the person their with
In my opinion, the correct answer is C. they found the charge and trouble very great, and they had little or no crop. This passage from Gulliver's Travels tells us about a weird and absurd innovation of "plowing" by spreading mast all over the field and letting pigs run for it and dig it out from the soil. This venture is obviously a disastrous one, and it is clearly an understatement to say that it brought great trouble and little results. The truth was probably that it brought no results at all, while being expensive, futile and foolish.
