Best answer
Right choice is (d) Constant

Explanation: The assumption that the cables are inextensible the main fact that comes out is that the cable length is constant throughout. Thus in the calculations also the fact that the length is constant makes a huge time saving tool. Thus the length of the cables are to be assumed constant if the assumption is taken as they are inextensible.
