revolutions, as we are all aware.
A clock hand moves by half (1/2) a revolution as a result

Now, assuming that the clock hand starts off at 12 as indicated by the red dotted line in the image, it rotates by

as indicated by the figure after making a half-revolution clockwise. As can be seen in the illustration, the minute hand of the clock is now in its final position at 6. Thus, the clock's hand comes to a standstill at 6.
Hence,the correct option is 3.
