The angle of deviation $\left(\mathrm{\delta }\right)$ vs angle of incidence (i) is plotted for a prism. Pick up the correct statements. 

Minimum deviation = 60° for minimum deviation 2i–A = 60°  
$$\begin{gathered} {\text{2×60}}^{\circ }-A={60}^{\circ }\Rightarrow A={60}^{\circ };1sin{60}^{\circ }=\mu sin{30}^{\circ } \\ \mu =\sqrt{3}{i}_1+i_2-A=d \\ {i}_1+70-A={65}^0 \end{gathered}$$
i₁ = 55° this curve is not symmetric in nature, So this is not a parabola.
