Answer 1

Right answer is (a) PNG

For explanation: If a transparent part of the image has rounded or diagonal corners we use PNG format. If we want semi opaque transparency or drop shadow there also this format is helpful. If the transparent part of the image has straight edges we use transparent GIF format.
