Solution
The correct option is B
From the top fibre to the neutral axis the distribution is parabolic and maximum value is obtained at neutral axis. The distribution remains parabolic below the axis but the values start reducing. For the bottom portion, the shear stress suddenly decreases due to increase in width of the section.
