C Correct answer
Explanation

Gallium has an unusually low melting point of about 30°C (86°F), which is near room temperature. This means gallium will melt in your hand. Sodium and potassium have low melting points but not as low as gallium, while sulfur is a non-metal. Gallium's low melting point makes it useful in high-temperature thermometers.
