In the diagram, D1D1 is a demand curve in the form of a straight line, while D2D2 is a rectangular hyperbola curve. Which statement is correct?
- AD2D2 is more elastic than D1D1 at point M.
- BD2D2 is more elastic than D1D1 at point N.
- CThe elasticity of demand increases on moving down both curves.
- DThe elasticity of demand is inelastic at point M on both curves.
