According to IS 456 cl 26.5.3.1 minimum reinforcement for any column is 0.8% and for the pedestal, it's 0.15%.
So the question is wrong as per IS 456 as it will never be zero to make it a plain concrete column.
Clarify if I am wrong.

This is stated in Old codebook SP 24-1983:
When the length of the compression member is less than three times the least lateral dimension it is called a pedestal.Pedestals can be of plain concrete also;
But in revised code IS 456 2000---the minimum reinforcement should be provided in all members to ensure the failure due to shrinkage, temperature.
