Which term describes the distortion where parts of the same object are magnified unequally?

• A. Magnification
• B. Elongation
• C. Unequal magnification of the same object
• D. Noise

Answer: (C)

Nonuniform enlargement across an object is being tested here. When different parts of the same object are magnified by different amounts, the image shows varying sizes within that object. This specific nonuniform or unequal magnification is what describes the distortion, making it distinct from uniform magnification (where the whole object grows the same amount), elongation (distortion along one axis due to misalignment), or noise (random fluctuations). So the phrase that captures this exact situation is unequal magnification of the same object.
