B. $${\frac{1}{5}^{{\text{th}}}}$$ of the span
C. $${\frac{1}{6}^{{\text{th}}}}$$ of the span

For Short column,
Span/Least lateral dimension < 12
but in case of long columns, it is > 12
For short column,
slenderness ratio is < 45
But in long column, it is > 45.
For short column,
Radius of gyration is MORE,
but in long columns, radius of gyration is LESS
For short column,
Loading failure is called- Crushing (due to compressive stress)
But in long column, failure is due to- Bulking or Crippling Load (due to Bulking stress).
Ans-(40) hoga
isn't it less then 12?
How? Can you please give reference? Because it's less than 12 according to IS 456
