Explanation
The minimum number of longitudinal bars provided in a circular column is actually six, not four. This answer is correct because the code requirements for reinforced concrete design specify that a minimum of six bars are needed to ensure proper distribution of loads and to prevent buckling. The QuizMaster of AnsweringExams.Com suggests remembering this by associating the number six with the six sides of a typical concrete column form, which helps to recall that at least six bars are required for a circular column. Other options regarding the minimum cross-sectional area of longitudinal reinforcement and the spacing of longitudinal bars are correct, making option D the incorrect statement. Competitive exams like PPSC, FPSC, CSS, NTS, MDCAT and ECAT test this topic. Practice more at AnsweringExams.Com.
