Solution

i) option C . \"point c\"

bending moment is maximum at center of the beam. and For I-section flexural stress is Maximum at flange. Hence at Point C flexural stress is maximum

J) option B \"Point b\"

Shear stress is maximum at supports and For I-section shear stress is maximum in web. Hence at point B shear stress is maximum
