Coloum or strut is more than 3.
Pedestal is less than 3.
Because of unsupported length. So the answer is more than three is correct.

Because of unsupported length. So the answer is more than three is correct.

Minimum reinforcement in the pedestal is 15%.

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.

In the case of a pedestal, the unsupported length does not exceed three times the least lateral dimension.
The pedestal can either be designed as a PCC or RCC structure.
Here, such column is made of PCC, so it may be a case of pedestal.

Slenderness ratio: Less than 3 for pedestal, 3-12 for short column, greater than 12 long column. So the answer is 3.

3 is right.
@Abhishek please read the question again.

Leff>3times of least lateral dimension--column and leff<3times of least lateral dimension-- pedestal. But in question saying the unsupported length (leff) not exceed their least lateral dimension. So, it is more than 3times and here the answer is 4times.
