Answer:
The option that provides the correct singular and plural noun is A. child-children.
Step-by-step 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 woman is women, and not woman's -that is the possessive noun; option C is not correct because the plural of moose is moose; and option D is not correct either because the plural of sheep is also sheep.
