When light is incident on the interface of glass and air as shown in the figure, the green light is just totally internally reflected. Then the emerging ray in air contains :

yellow, orange, red
violet, indigo, blue
all colours
all colours except green

$λ_{R} > λ_{G} > λ_{V}$
$μ_{R} < μ_{G} < μ_{V}$
$(i_{c})_{R} > (i_{c})_{G} < (i_{c})_{V}$
it follows from VIBGYOR that the critical angles for yellow, orange and red are greater than the critical angle for green.
Hence, option A is correct.
