Consider the following statements regarding Solder and soldering alloys: 1. Solder is a eutectic alloy of lead and tin, meaning its melting point is lower than that of either pure lead or pure tin. 2. Rosin-core solder contains an acidic flux that chemically cleans the metal surfaces during soldering. 3. Lead-free solders commonly use a combination of tin, copper, and silver to replace toxic lead. Which of the statements given above are correct?

Options:

• A: 1 and 2 only
• B: 2 and 3 only
• C: 1, 2 and 3
• D: 1 and 3 only
