Phase diagram of a compound is shown below 
The slopes of the lines $\mathrm{OA}, \mathrm{AC}$ and AB are $\tan \frac{\pi}{4}, \tan \frac{\pi}{6}$ and $\tan \frac{\pi}{3}$ respectively. If melting point and $\Delta \mathrm{H}$ of melting are 300 K and 3 kJ mole ${ }^{-1}$ respectively, the change in the volume on melting is
The slopes of the lines $\mathrm{OA}, \mathrm{AC}$ and AB are $\tan \frac{\pi}{4}, \tan \frac{\pi}{6}$ and $\tan \frac{\pi}{3}$ respectively. If melting point and $\Delta \mathrm{H}$ of melting are 300 K and 3 kJ mole ${ }^{-1}$ respectively, the change in the volume on melting is(a)$10 \tan \frac{\pi}{3}$
(b)$10 \tan \frac{\pi}{4}$
(c)$10 \cot \frac{\pi}{3}$
(d)$10 \cot \frac{\pi}{4}$
