The correct answer is (b) Mercury.
· Mercury is the only metal that is in a liquid state at room temperature (around 25°C or 77°F). It is unique among metals due to its low melting point of -38.83°C, which allows it to remain in a liquid form at standard conditions.
Information Booster:
· Calcium , Potassium , and Sodium : These metals are solid at room temperature and have relatively high melting points compared to mercury.
