The melting point of lead is 327.46℃. So when the temperature is 328℃, the lead will change from a solid to a liquid. When the temperature is 874 or 601℃, the lead is already liquid. So the answer is (3).

Answer: The correct answer is option 3.

Explanation: The phase change from solid to liquid occurs when the substance is at a constant temperature. That temperature is known as the melting point of that substance.

\(Solid\rightleftharpoons Liquid\)

We are asked the temperature at which Lead changes from solid to liquid. As, the melting point of lead is 328°C, so this is the temperature at which Lead changes from solid to liquid.

Hence, the correct option is 3.
