Explanation:

Step1: Convert units to same unit (bytes)

1 GB = 1024 MB, 1 MB = 1024 KB, 1 KB = 1024 B. So, "performance.mov" (1.2 GB) = 1.2×1024×1024×1024 B ≈ 1.2×$10^{9}$ B; "winners.jpg" (2 MB) = 2×1024×1024 B = 2097152 B; "history.epub" (800 KB)=800×1024 B = 819200 B; "howto.epub" (320 KB)=320×1024 B = 327680 B; "moves.csv" (240 B)

Step2: Compare sizes

1.2×$10^{9}$ B > 2097152 B > 819200 B > 327680 B > 240 B, which means 1.2 GB > 2 MB > 800 KB > 320 KB > 240 B

Answer:

D. "performance.mov" (1.2 GB), "winners.jpg" (2 MB), "history.epub" (800 KB), "howto.epub" (320 KB), "moves.csv" (240 B)
