In an FCC crystal with lattice parameter $a$, consider the reaction of two leading partial dislocations, AB and CD, at the line of intersection of their slip planes (111) and (11$\bar{1}$), respectively, as shown in the figure below. Dislocations, AB and CD, have Burgers vectors $\vec{b}_1$ and $\vec{b}_2$ , respectively, as given in the figure. Which one of the following options for the slip plane and the Burgers vector of the resulting dislocation is correct?
