The question is about adverbs and adjectives that relate to the measure of quantity. They are called Quantifiers. The correct sentence, therefore, is:
How much luggage do you have, Mrs. Parker? (Option B).
A quantifier refers to a word that is usually placed before a noun to express the quantity of the object.
For example, "some milk."
In most cases, quantifiers may be followed by a noun.
For example, Do you want some bread? – Just a little.
