The motion of a sphere moving on a rough horizontal surface changes from pure sliding (without rolling) to pure rolling (without slipping). In this process, the force of friction
(`i`) intially acts opposite to the direction of motion and late in the direction of motion
(`ii`) cause linear retardation
(`iii`) causes angular acceleration
(`iv`) stops acting when pure rolling begins
A. (`i`),(`ii`)
B. (`i`),(`ii`),(`iii`)
C. (`ii`),(`iv`)
D. (`ii`), (`iii`),(`iv`)
