							What is concentration?Concentration: concentraion is amount of solute present in per unit of soulution.  The amount of solute/solution can be represented by anything (weight,mole,volume). Thus we can represent concentration in many ways e.g Molarity, Molality, Mole fraction etc  what is molarity?molarity is "number of moles of solute are present in 1 litre of solution”$Molarity = \frac{no. of moles of solute}{volume of solution (litre)}$ What is Normality?normality or equivalent concentration is molar concentration divided by equivalence factor or n factor$Normality = \frac{C}{n}$ Note: here molar concentration is same as molarity so $Normality = Molarity *n$                                    where n= n factor What is n factor?i will not go into deep, but remember n factor for acid is no. of H+ ions it can furnishn factor of some acids are:HCl = 1H2SO4=2HNO3=3H3PO4=3  Now Coming to your Question:Using the n factors and formula given, find molarity(i.e Concentration) of each acid with fiven Normality $Molarity = \frac{Normality}{n}$ On calculating you will find correct option is b
