B Correct answer
Explanation

Gallium has an unusually low melting point of approximately 30°C, just above typical room temperature (20-25°C). When placed on a human palm at body temperature (~37°C), it readily melts from solid to liquid. This property makes gallium a classic classroom demonstration metal.
