Explanation:

The past experience that whenever the Centre was weak the country fell a prey to foreign invaders. It was in keeping with the tendencies prevailing in other federations of the world. The fissiparous tendencies prevailing in the country at the time of the enactment of the Constitution. Hence option 2nd is incorrect.
