Which premature failure occurs when insufficiently braced rebar buckles?

💡 Explanation

Reduced moment capacity occurs because lateral torsional buckling reduces rebar's effective cross-section resisting bending. The unbraced rebar yields prematurely, causing reduced flexural capacity, therefore 'A' is correct, rather than carbon steel corrosion or creep, under normal conditions.
