An instantaneous configuration of a four-bar mechanism, whose plane is horizontal, is shown in the figure below. At this instant, the angular velocity and angular acceleration of link $${Q_2}\,\,A$$ are $$\omega = 8\,\,rad/s$$ and $$\alpha = 0$$, respectively, and the driving torque $$(T)$$ is zero. The link $${Q_2}\,\,A$$ is balanced so that its center of mass falls at $${Q_2}.$$ At the instant considered, what is the magnitude of the angular velocity of $${O_4}B?$$

A
$$1$$ rad/s
B
$$3$$ rad/s
C
$$8$$ rad/s
D
$$64/3$$ rad/s
