1. which of the following represents the altitude of this cylinder? . . line bc. segment bc. bc. ray cb

I saw the image that should have accompanied this problem. The altitude of the cylinder is SEGMENT BC.

Altitude is defined as the perpendicular segment from the plane of one base to the plane of the other base. When you see a cylinder that has a height in unit measure, it simply means that the height is the length of the cylinder's altitude.
