10. D and D' in the figure below are parallels. The quantity is measured on the horizontal axis. A straight ray going through the origin intersects D and D' at e and e'. Compare the elasticity of the demand functions D and D' at points e and e'. Where is the demand more elastic? ray starting at (0,0) P e,' e D' D Q a. D at pointe. b. D' at point e'. C. The elasticities are equal at e and e'. d. More information is needed to answer this
