Explanation:

Step1: Recall magnetic - material property

Magnets stick to magnetic materials. If they don't stick, the object may not be magnetic.

Step2: Analyze each option

• Option A: If the refrigerator body isn't made of magnetic material, magnets won't stick. This is a valid reason.
• Option B: Earth's magnetic field is very weak and not strong enough to prevent a small magnet from sticking to a magnetic surface. So this is incorrect.
• Option C: Refrigerators are not magnetic sources with poles. This option is wrong as it mis - applies the concept of magnetic poles.
• Option D: A refrigerator being plugged in or not has no relation to a magnet sticking to it. This is incorrect.

Answer:

A. The body of the refrigerator isn't made of magnetic material.
