Perry observes the opposite, parallel walls of a room.
In how many lines do the planes containing the walls intersect?

a) 0
b)1
c)2
d)3

Answer 1

"0" would be the number of lines among the choices given in the question that the planes containing the walls will intersect. The correct option among all the options that are given in the question is the first option or option "A". As the walls are parallel to each other, so the planes containing the walls would never intersect.
