detailed solution

Correct option is A

Fa¯=m(a¯a)=ma2a2= always+ve m=always +ve, so Fa¯ is + ve 

Force or acceleration and displacement are  always in opposite direction hence so F.r or a.r are always negative

V and r sometimes in the same direction sometimes in opposite direction so it could be +ve or -ve.
