Two wheels, Wheel A and Wheel B$,$ are each rotating about an axis through their centers with angular velocities that are constant. Wheel A has a radius $r_0$ and rotates one revolution in a time interval $t.$ Wheel B has a radius of $2r_0$ and rotates one revolution in a time interval $2t.$ Which of the following correctly describes the linear speed $v_A$ of a point located on the edge of wheel A and the linear speed $v_B$ of a point located halfway between the center and the edge of Wheel B$?$

$v_A>v_B$

$v_{A}0$

$($D$),v_A=v_B=0$
