JPEG is typically chosen for:
A. Photographs, where some loss of quality is acceptable✓ 答案
B. Line-art logos that need perfectly sharp edges only
C. Program source code that must stay exact
D. Uncompressed audio recording
解說
JPEG suits photographs because its loss is hard to notice on natural images. Diagrams, text and code keep sharp edges that show artefacts, so lossless formats such as PNG are preferred there.
