a) foxsb) foxesc) foxend) foxiesThe correct answer is: b) foxes Explanation: Most nouns ending in -x, -s, -sh, or -ch form their plural by adding -es (not just -s). Example: box → boxes bus → buses brush → brushes fox → foxes Why the others are wrong: a) foxs – Incorrect, because nouns ending in -x don’t just add -s. c) foxen – Incorrect, this is an old/archaic plural form used for some words (like ox → oxen) but not for “fox.” d) foxies – Incorrect, this would mean “small or cute foxes” in a slang/diminutive sense, not the standard plural. Correct plural: foxes.
