ok so I am assuming that they kinda mean the orientation of the cars in relation to other cars and the curb
angled parking, that is like the slanted parking spaces that is hard to judge how far you are and bump into the car in front, not easy
perpendicular, this is like angled parking but normal, the cars are not slanted, easy peasy
regular, define regular, maybe this is the answer
paralel parking is slightly difficul
so either b or c
