Which grayscale depth corresponds to 256 distinct gray levels?

Explanation:
Bit depth determines how many distinct gray shades a pixel can represent. Each additional bit doubles the number of possible levels, since levels = 2^bits. To achieve 256 distinct gray levels, you need 2^8, which means 8 bits per pixel. So, 8-bit depth provides 256 grayscale levels (values 0 through 255). The other options would give 16, 32, or 8 levels respectively, which are fewer than 256.
