A disc of radius `R` rolls without slipping at speed `v` along positive `x`-axis. Velocity of point `P` at the instant shown in Fig. is
A. `v_(p)=(v+(vrsintheta)/(R))hati+(vrcostheta)/(R)hatj`
B. `v_(p)=(v+(vrsintheta)/(R))hati-(vrcostheta)/(R)hatj`
C. `v_(p)=v+(vrsintheta)/(R)hati+(vrcostheta)/(R)hatj`
D. `v_(p)=v+(vrsintheta)/(R)hati-(vrcostheta)/(R)hatj`
