Consider the following statements regarding Nickel-based alloys: 1. Monel metal is an alloy of nickel and copper, known for its high resistance to corrosion by acids and seawater. 2. Nichrome is an alloy of nickel, chromium, and iron, widely used as heating elements in electrical appliances due to its high resistivity and high melting point. 3. Constantan is an alloy of copper and nickel whose electrical resistivity remains relatively constant over a wide range of temperatures. Which of the statements given above are correct?

Options:

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