A roller bottle culture vessel perfectly cylindrical in shape having inner radius (r) = 10 cm and length (l) = 20 cm was fitted with a spiral film of length (L) = 30 cm and width (W) = 20 cm. If the film can support 10^5 anchorage dependent cells per cm^2, the increase in the surface area after fitting the spiral film and the additional number of cells that can be grown respectively are (A) 1200 cm^2 and 12 x 10^7 cells (B) 600 cm^2 and 6 x 10^7 cells (C) 600 cm^2 and 8300 cells (D) 1200 cm^2 and 8300 cells
