In an experiment for determination of refractive index of glass of a prism by

i - \delta ,

plot it was found thata ray incident at angle

{35^ \circ }

, suffers a deviation of

{40^ \circ }

and that it emerges at angle

{79^ \circ }.

In that case which of the following is closest to the maximum possible value of the refractive index?

A
$1.7$
B
$1.8$
C
$1.5$
D
$1.6$
