Which of the following statement is `//` are correct about the refraction of light from a plane surface when light rays is incident in denser medium. `[` C is critical angle `]`

Options

A. The maximum angle of deviation during refraction is `(pi)/(2)-theta_(C )`, it will be at angle of incidence is `theta_(C )`
B. The maximum angle of deviation for all angle of incidences is `pi-2theta_(C )`, when angle of incidence is slightly greater than `theta_(C )`
C. If angle of incidence is less than `theta_(C )` then deviation increases if angle of incidence is also increased
D. If angle of incidence is greater than `theta_(C )` then angle of deviation decreases if angle of incidence is increased
