Which does not represent a possible intersection of a line and a right cylinder?
a. 3 points
b. 2 points
c. 1 point
d. a segment
A?

looks good to me. If more than two given points are on a line, then all points between them are.
Actually, B would indicate that the cylinder is just the surface, while D seems to indicate that the cylinder is solid. The question is ambiguous. At any rate, A is not a possible choice.
