(a) Change in cross-section area only
(b) Change in cross-section only
(c) Change in cross section area as well as change in cross-section

This question was addressed to me at a job interview.
Question is from Some Comments on Mesh Generation and Imposition of Boundary Conditions in section Single Variable Problems of Finite Element Method
