Which Is Correct? There Should Not Be a Need, or It Will Not

Which is correct?
There should not be a need, or it will not be advisable, to make many interim applications in an action because …

A) the cost of making them will disproportionately increase the costs for the client.
B) the court manages the progress of a case and therefore there is little point in legal representatives seeking to modify the directions made for their clients.
C) case management, track guidelines and the need for proportionality and cooperation make it less likely that interim applications will be made.
D) in defended cases there will never be a need to make an interim application as the court will set the directions and hear any representations by both parties at the allocation hearing.
