The option that provides the correct singular and plural noun is A. child-children.
Explanation:
Plurals in English can be tricky. Within this list, the option that provides the correct singular and plural noun is A. child-children, that is an irregular plural form.
Option B is not correct because the plural of <em>woman </em>is <em>women</em>, and not <em>woman's</em> -that is the possessive noun; option C is not correct because the plural of <em>moose </em>is <em>moose</em>; and option D is not correct either because the plural of <em>sheep </em>is also <em>sheep</em>.
A: child-children because B is noun-possesive noun C is noun-verb and D is wrong because the plural version of sheep is sheep(there are a few other exceptions along with it)
