Hint: To calculate the molarity we need to find the number of moles of solute dissolved in solution. Then we have to find the volume of the solution in litres. And dividing moles of solute by litres solution. We should start with the basic definition of a molar solution for answering this question.

Complete step-by-step answer:

We should know that molar concentration is a measure of the concentration of a chemical species in particular of a solute in a solution in terms of the amount of substance for a unit volume of solution.

According to the definition of one molar solution is a solution in which one mole of a compound is dissolved in a total volume of one litre.
Therefore, the correct answer to the question as Option B.

We can explain the concept of one molar solution with the help that a one molar solution will contain 1 mole of a compound. This entire 1 mole of a compound will be dissolved in a total of 1 litre of solution.

Note: Molarity is important in chemistry because it is the measurement of concentration. Molarity of solution is the way to figure out how much of a specific element or compound has been dissolved or used in a certain amount of the solution.
