Solution:The Second Five-Year Plan was drafted under the leadership of PC Mahalanobis. KN Raj drafted sections of India’s first Five-Year Plan. Hence, statement 1 is incorrect. The Second Five Year Plan focused on heavy industries and followed socialist pattern of society as its goal.
Since savings and investment were growing in this period, a bulk of these industries like electricity, railways, steel, machineries and communication could be developed in the public sector. Thus, statement 2 is correct.
However, the Second Five-Year Plan had its problems as well, because industry attracted more investment than agriculture, the possibility of food shortage became adverse. So, the planners found balancing industry and agriculture really difficult. Hence, statement 3 is also correct.
