In each of the questions, four different ways of presenting an idea are given. Choose the one that conforms most closely to Standard English usage.
Explanation:
The subject, ‘running of a large business’ or ‘running of large businesses’ is singular and should take a singular verb (consists) and not plural (consist). With that, options 1 and 4 can be ruled out. In C, it should be ‘more than its cost.’ Option 3 can therefore be eliminated. Statement B is correct in this regard (‘more than it costs’ is correct).
Hence, the correct answer is option 2.
