Correct answer: B
First, convert the video memory to bytes: 8 MB = 8 × 1024 × 1024 bytes. Each pixel requires 64 bits, which equals 8 bytes. The maximum number of pixels supported is (8 × 1024 × 1024) ÷ 8 = 1,048,576 pixels. Compare the pixel count of each resolution option against this maximum to determine which fits within the memory limit.
