Question

Graphics Interchange Format (GIF) is a ____ RGB bitmap image format for images with up to 256 distinct colors per frame.

Options

A8-bit
B32-bit
C16-bit
D24-bit

Explanation

GIF uses an 8-bit color depth, which allows for a palette of up to 2^8 = 256 distinct colors per frame. This limited palette makes GIF suitable for simple graphics, logos, and animations, but not for photographs. The format uses lossless LZW compression. Higher bit-depth formats like 16-bit (65,536 colors), 24-bit (16.7 million colors â€” standard 'true color'), and 32-bit (24-bit color + 8-bit alpha channel) support far more colors and are used in formats like PNG, JPEG, and TIFF.
