Hint: The acid which is known as “the king of acids” is a strong acid. This is the most widely used chemical and has a very important role in chemical industries. Now, try to identify the correct answer among all the options provided.

-Option A, Acetic acid is also called ethanoic acid, the most important of the carboxylic acids with the chemical formula $CH_{ 3 }COOH$. A dilute solution of acetic acid produced by fermentation and oxidation of natural carbohydrates is called vinegar.
-Option B, Phosphoric acid, also known as orthophosphoric acid or phosphoric(V) acid, is a weak acid with the chemical formula $H_{ 3 }PO_{ 4 }$. The pure compound is a colorless solid.
-Option C, Oxalic acid is an organic compound with the formula $C_{ 2 }H_{ 2 }O_{ 4 }$. It is a white crystalline solid that forms a colorless solution in water.
-Option D, Sulfuric acid, is a mineral acid composed of the elements sulfur, oxygen, and hydrogen, with molecular formula $H_{ 2 }SO_{ 4 }$. It is called the king of acid because of its direct and indirect applications in the manufacture of many chemicals including fertilizers. So we can say, it is ideal to call sulphuric acid as king of chemicals.
