Well, if I were to find how many more liters I would need, I would do the following:$$4/10=.4$$ This is 1/10th of the initial serving amount or .1, but I need .3 so I'm going to multiply that by 3. $$.4 * 3=1.2$$ This is how much more I need. So I add the initial amount to this amount:$$4+1.2=5.2$$ B is equal to 5.2. Though I am unfamiliar with the methods used in the question you provided. But yes, B is the answer.
