The solution is B) A base.
Step-by-step explanation:
The substance can be classified into different category based upon two criteria namely physical properties and chemical properties. The color, texture, appearance, smell, etc., are considered as physical properties whereas the boiling and melting point, etc., are considered as chemical properties.
When a solution tastes bitter and is soapy to touch they are called base. If a solution is sour in taste and is corrosive it is acid. Esters are sweet in smell and have variety of taste and appearance.
