B Correct answer
Explanation

Gallium has an unusually low melting point of 29.76°C (approximately 85.6°F), which means it becomes liquid at normal room temperature (typically 20-25°C). While mercury and bromine are also liquids at room temperature, mercury is the only other metal that's liquid under standard conditions, and it's not listed among the options.
