It is RCC Column. Hence, IS:456-2000 is only applicable. For long columns, SR should be more than 12 but less than 60.

L/r is greater than 40 is long column.

A short steel column is one whose slenderness ratio does not exceed 50 in case of steel column.

If effe Length/radius of gyration >=50 it's call long column and for mild steel it's value is 80.

Long column 120 greater than medium column 32-120, and short column less than 32 for steel design.

A short steel column is one whose slenderness ratio does not exceed 50; an intermediate length steel column has a slenderness ratio ranging from about 50 to 200, and its behavior is dominated by the strength limit of the material, while a long steel column may be assumed to have a slenderness ratio greater than 200 and its behavior is dominated by the modulus of elasticity of the material.

Please read the question carefully. Slenderness ratio is another thing. If slenderness ratio is less than 50 then it is short column but between 50 and 200 then intermediate column and above 200 then long column.
If the ratio of the effective length of the column and least lateral dimension is less than 12 then it is a short and otherwise long column.
If the ratio of the effective length of the column and least lateral dimension is less than 12 then it is a short and otherwise long column.

10<Leff/Rmin<=40 short column 40 include in short column condition.
But for long column Leff/Rmin>40 Slenderness.
But for long column Leff/Rmin>40 Slenderness.

Yes it's 60.

Slenderness ratio is the ratio of the length of a column and the least radius of gyration of its cross section. Often denoted by lambda. It is used extensively for finding out the design load as well as in classifying various columns in short/intermediate/long. Example- Short Steel column - lambda is less than 50.
