Answer 1

Right choice is (a) there are so many colors in the picture

The explanation: When we have different colors in a picture we use JPEG format. But when images have few colors or have large areas of the same color we use PNG or GIF format. Photographs that contain sky, snow, grass etc. are not suitable for PNG or GIF format.
