The figure shows the plan view of a single-storey masonry shear wall building with rigid roof diaphragm. The traces of locations of the centre of mass (CM) and the centre of stiffness (CS) are as shown. Neglecting accidental eccentricity, the direction of the twisting moment on the diaphragm, for the lateral force direction shown, is

• A. Clockwise
• B. Anticlockwise
• C. Opposite to the direction of lateral force
• D. None of the above
