A man thinks about 4 arrangements as shown to raise two small bricks each having mass m. Which of the arrangement would take minimum time ?

Seven identical circular planar disks, each of mass M and radius R are welded symmetrically as shown. The moment of inertia of the arrangement about the axis normal to the plane and passing through the point P is :
