When the gap is closed without placing any object
\( \mathrm{P} \)
in the screw gauge whose least count is \( 0.005 \mathrm{~mm} \), the \( 5^{\text {th }} \) division on its circular scale coincides with the reference line on main scale, and when a small sphere is placed reading on main scale advances by 4 divisions, whereas circular scale reading becomes five times to the corresponding reading when no object was placed. There are 200 divisions on the circular scale. The radius of the sphere is
(A) \( 4.10 \mathrm{~mm} \)
(B) \( 4.05 \mathrm{~mm} \)
(C) \( 2.10 \mathrm{~mm} \)
(D) \( 2.05 \mathrm{~mm} \)
