The correct answer is:
$\mathrm{C}_6 \mathrm{H}_5-\stackrel{+}{\mathrm{C}}-\mathrm{C}_6 \mathrm{H}_5$
Due to more possibility for delocalisation in
$\mathrm{C}_6 \mathrm{H}_5-\stackrel{+}{\mathrm{C}}-\mathrm{C}_6 \mathrm{H}_5$ (of $\pi$-electrons),
$\mathrm{C}_6 \mathrm{H}_5-\stackrel{+}{\mathrm{C}}-\mathrm{C}_6 \mathrm{H}_5$ is the most stable ion.
$\mathrm{C}_6 \mathrm{H}_5-\stackrel{+}{\mathrm{C}}-\mathrm{C}_6 \mathrm{H}_5$ (of $\pi$-electrons),
$\mathrm{C}_6 \mathrm{H}_5-\stackrel{+}{\mathrm{C}}-\mathrm{C}_6 \mathrm{H}_5$ is the most stable ion.
