Hint: Acids are generally those substances that have pH values less than 7, turn blue litmus paper into red, and have sour taste rather than these the main property of acid it is capable of donating a proton and also we can say that it is capable of forming a covalent bond.

Complete step by step answer:
Mineral acid is also known by the other name inorganic acids and it is defined as an acid derived from one or more inorganic compounds. Mostly all of the mineral acids form hydrogen ions and conjugate base when dissolved in water. Mineral acids range from superacids i.e. strong acids to very weak acids. - - These are soluble in water and insoluble in organic solvents.
The main example of mineral acid is hydrochloric acid, nitric acid and sulphuric acid which are manufactured for commercial use in large plants. These acids are also used directly for their corrosive property. But citric acid is not kept in the category of mineral acid because it is not an inorganic compound. It is an organic compound that is found in citrus fruits which are used as a natural preservative and weak organic acids. So, the correct answer is “Option B”.

Note: Mineral acids have the property that in their aqueous solution they dissociate into their ions and citric acid is mostly used as an anticoagulant and has a chelating property due to these properties it is not kept in the case of inorganic acid or mineral acid.
