Option B bed/ joint due to east 30° will be unstable and cause landslide

![eduncle-logo-app]()
in option A it's not written 20 deg due east .. it's written 20 deg due west..
![eduncle-logo-app]()
why option C 60 degree due east is not possible?
![eduncle-logo-app]()
because the necessary condition is that the bed/joint slope must be less and should be in the same direction.

in higher studies you will be clear about it. it's a part of engineering geology
