$22 \cdot 2$ In the plane of one face of a cube, draw any line, then the number of edges of the cube that are skew to it is
(A) 4 or 5 or 6 or 7 .
(B) 4 or 6 or 7 or 8 :
(C) 6 or 7 or 8 .
(D) 4 or 5 or 6 .
(2nd "Hope Cup" National Mathematics Invitational Competition, 1991)
[Solution] In the following figures (1) and (4), the number of edges that are skew lines with $l$ are 4, 6, 7, 8, respectively.
Therefore, the correct choice is $(B)$.
