I had been asked this question in an interview for job.
The origin of the question is Projections of Solids with Axis Inclined to Vertical Plane and Parallel to Horizontal Plane topic in division Projection of Solids of Engineering Drawing
For explanation: For given positions of solid the solid is made acute angle with V.P and previously given the axis is perpendicular to V.P so the front view gives the circle and next with some given angle shape will change to rectangle with circular ends.
