Which one of the following problems was India faced with after independence?

The passage discusses how 'Coordination of policies was difficult even when the Congress Party was in power both in the States and at the Centre; when a Congress government in Delhi was confronted with non-Congress parties in office in the States, it became much harder.' This describes lack of coordination between the Central and State Governments. The passage focuses on this Centre-State problem, not military attacks or production issues. Hence (2) is correct.
