Show answer and explanation

Answer: B. Cutting nails

Why "Cutting nails" is a physical change:
No New Substance: When you cut your nails, the material (keratin) remains exactly the same; only the size and shape are altered.
Physical Property Alteration: It is a change in a physical property (length) rather than a chemical one
