D. 50 is correct.

L to lateral dimension > 12.
Or.
Slenderness ratio greater than 120 is a long column.
Or.
Slenderness ratio greater than 120 is a long column.

Yes, 40 is the right answer.

According to IS: Code 456-1978.
S.R .is less than 12 that's called a short column.
And S. R. is equal to up in 12 that's called long column.
S.R .is less than 12 that's called a short column.
And S. R. is equal to up in 12 that's called long column.

Short RCC Column =<12.
Long RCC Column >12.
Short Steel column, =<50.
Intermediate Steel Column >40 & <200.
Long Steel Column >200.
Long RCC Column >12.
Short Steel column, =<50.
Intermediate Steel Column >40 & <200.
Long Steel Column >200.

@All.
"The unsupported length between end restraints.
Shall not exceed 60 times the least lateral dimension of a column.
IN THE ABOVE LINE ITS NOT WRITTEN THAT IF IT EXCEEDS 60 THAN IT WILL BE A LONG COLUMN.
ACCORDING TO IS CODE 456, PAGE NUMBER 41 CLAUSE 25.1.2 STATED THAT;
"A compression member may be considered as short.
When both the slenderness ratios Lex/D and Ley/b are less.
Than 12".
SO, SLENDERNESS RATIO IS;
(EFFECTIVE LENGTH/LEAST LATERAL DIMENSION).

Pedestal =less than or equal to 3,
Short column= between 3 to 12,
Long column = 12 to 60.
Short column= between 3 to 12,
Long column = 12 to 60.

This is based on l (effective) /radius of gyration.
