Concept:The word "less" is correctly used for uncountable or measured quantities (e.g., "less sugar," "less time"), while "fewer" is used for countable items (e.g., "fewer people," "fewer states").
Explanation:To identify the correct sentence, apply the grammar rule that "less" refers to amount or quantity among things that are measured, and "fewer" refers to numbers among things that are counted.
Option A: "There are less than fourteen people attending the seminar" — "people" are countable, so "fewer" should replace "less."
Option B: "Less states are fulfilling the targets set by the union ministry" — "states" are countable, so "fewer" is required instead of "less."
Option C: "There is less sugar in the tea than what I asked for" — "sugar" is an uncountable substance measured by quantity, so "less" is used correctly here.
Option D: "There are very less days left before the examinations begin" — "days" are countable, so "very few" or "fewer" should replace "very less."
Only option C demonstrates the correct usage of "less."
Answer:Option C is the correct sentence.
