  • A. d
  • B. a
  • C. e
  • D. c
Correct Answer: Option B - As per IS 800 : 2007 Cl. 7.1.2.2, Buckling class of cross-section– (i) Channel, angle built-up member, T and solid sections about any axis are related to buckling class C. (ii) Hollow section– • Hot rolled hollow section buckling about any axis - Class a • Cold formed hollow section buckling about any axis - Class b
