Concept:Choose the correct quantifier based on whether the noun is countable or uncountable.
Explanation:The word “water” is an uncountable noun.
“A few” and “few” are used only with countable plural nouns, so options A and B are wrong.
Option C says “a lot”, but the correct expression is “a lot of water”, so C is also unsuitable.
For uncountable nouns, use “a little” to mean “some amount”.
Thus, the sentence becomes: “There is a little water in the fridge.”
Answer:D. a little
