We are aware that the temperature at which a liquid freezes is known as the freezing point. The freezing points of liquids vary based on their chemical composition.
The atomic number of the chemical element mercury is 80. It appears in group 12, period 6, of the periodic chart. Mercury marks the conclusion of the third series of transition metals. In chemistry, the word "Hg" stands for mercury.
The only metal that is liquid at conventional temperature and pressure is mercury, a heavy d-block element. Because of this, mercury is frequently referred to as a liquid metal.
Our bodies are hazardous to mercury. Even skin can be used to absorb it. Mercury toxicity from ingestion can result in both acute and chronic poisoning.

In addition to producing thermometers and other mechanical and electrical equipment, its ability to produce amalgam has significant applications in the medical field. Dental fillings typically made of amalgam are utilised.
Let's now talk about mercury's freezing point.
The freezing point of mercury is far lower than that of any stable metal.
When the temperature reaches 38.83 C, it freezes.
We must convert Celsius to Kelvin since the alternatives are offered to us in kelvin units.
We are aware that 273 kelvin is equal to degree celsius.
38.83 ^oC will thus equal 273 + (-38.83) Kelvin, or 234.3 Kelvin.

Hence, the correct answer is B.
