It should be applicable to long and short column both, why option D?

Rankine is valid for short column and long column and also valid for intermediate column.

You are right @Akshara.

Since the Rankine formulae is a combination of the Euler and crushing load for a strut.
For a very short strut Pe is very large hence 1/ Pe would be large so that 1/ Pe can be neglected.
Thus PR = Pc, for very large struts, Pe is very small so 1/ Pe would be large and 1/ P c can be neglected, hence PR = Pe
The Rankine formulae is therefore valid for extreme values of 1/k. It is also found to be fairly accurate for the intermediate values in the range under consideration.

Rankine-Gordon's empirical formula is known as Rankine's formula.
