If the frame buffer has 8 bits per pixel and 8 bits are allocated for each of the R, G, B components, what would be the size of the lookup table?
Answer: C. 768 bytes — The frame buffer uses 8 bits per pixel, creating an index space of 2^8 = 256 entries in the lookup table. Each entry stores 8 bits for Red, Green, and Blue…

Correct answer: C
The frame buffer uses 8 bits per pixel, creating an index space of 2^8 = 256 entries in the lookup table.
Each entry stores 8 bits for Red, Green, and Blue components (24 bits total), equaling 3 bytes per entry.
Multiplying the number of entries by the size per entry gives 256 * 3 = 768 bytes.
