Explanation:

To determine why Maddie is careful with the etchant for copper plates, we analyze each option:

• Option A: Etchants for copper (like ferric chloride or acids) are acidic and can cause harm if mishandled (e.g., burns, corrosion).
• Option B: Etchant’s weight is not a primary safety concern for handling.
• Option C: Etchant is a liquid (or solution), not “sharp” (a property of solids/edges).
• Option D: Standard etchants for copper are not typically hot; acidity is the key hazard.

Answer:

A. The etchant is acidic.
