A. He  
B. Ag  
C. Hg  
D. Zn

NursesPath · Accepted Answer

Correct Answer: (C)Hg. 
Rationale:  Hg (Mercury) because it is the only element among the options that is a liquid at room temperatureA. He (Helium): Helium is a gas at room temperature. It is a noble gas and exists as a gas under normal conditions, so it is not a liquid at room temperature.B. Ag (Silver): Silver is a solid at room temperature. It is a metal with a melting point of 961.8°C, far higher than room temperature, making it a solid under normal conditions.C. Hg (Mercury): Mercury is the only metal that is liquid at room temperature. Its melting point is -38.83°C, which is well below room temperature, allowing it to remain in liquid form at standard conditions.D. Zn (Zinc): Zinc is a solid at room temperature. Its melting point is 419.5°C, so it remains solid under typical conditions.Conclusion:The correct answer is C.. Unlike most metals, mercury remains in liquid form due to its low melting point, which allows it to be liquid at standard room temperatures.
