Column AB is close to a truss tower. The below figure shows two views of AB. Left hand side of the below figure shows AB in XZ plane and right hand side of the figure shows AB in YZ plane. Consider supports at two ends of AB in XZ and YZ planes and answer the following question. The column is planned to be strengthened against buckling by building a single lateral support to the adjacent truss. Contractor is considering all options. To which joint of the truss (D, E, F, G, H or I) could the lateral support be joined? Select all the plausible answers.
