Correct Answer:
B. Mice
The correct answer is Mice. The word "mouse" is an irregular noun, and its standard plural form is mice. This follows a vowel‑change pattern inherited from Old English.
Irregular Plural Formation
- Standard Plural — Mice: Just as "louse" becomes "lice" and "goose" becomes "geese," "mouse" transforms to "mice" by changing the internal vowel sound (a process called i‑mutation or vowel mutation).
- Special Case — Computer Mice: For the computer pointing device, both "mice" and "mouses" are sometimes used, but "mice" is far more common and accepted in formal English. The question refers to the general plural, which is unequivocally "mice."
- Incorrect Forms:
- Mouses: Occasionally used for computer devices, but not standard.
- Mices: A double plural — incorrect.
- Mousers: A completely different word meaning a cat that catches mice.
Thus, the plural of "Mouse" is Mice.
