(i) Light can be totally internally reflected when it passes from `B` to `A`
(ii) Light can be totally internally relected when it passes from `A` to `B`
(iii) Critical angle for total internal reflection is `i_(B)-i_(A)`
(iv) Critical angle between `A` and `B` is `sin^(-1)((sini_(A))/(sin i_(B)))`

Options
