Fourteen identical resistors, each of resistance r each connected as shown in figure. Pick the incorrect alternative(s)

By the symmetry of circuit the points (B, H) and (D, F) are at same potential. So Resistors in branches ‘BH’ and ‘DF’ are ineffective. The equivalent circuit is

From current distribution for series and parallel combinations
$\begin{array}{l}{\mathrm{i}}_1=\mathrm{i}/2,{\mathrm{i}}_2=\mathrm{i}/2,{\mathrm{i}}_3=\mathrm{i}/5,\\ \mathrm{i}=5{\mathrm{i}}_3\\ \\ \frac{{\mathrm{i}}_3}{{\mathrm{i}}_1}=\frac{2}{5}\Rightarrow {\mathrm{i}}_3=\frac{2{\mathrm{i}}_1}{5}\\ {\mathrm{R}}_{\mathrm{AE}}=\mathrm{r}/2+\frac{\mathrm{r}}{5}+\frac{\mathrm{r}}{2}=\frac{6\mathrm{r}}{5}=1.2\mathrm{r}\end{array}$
