Answer:
B Cynthia wears her lucky shoes
Step-by-step explanation:
A doesn't work as a sentence because who is "she?" What happens whenever she plays soccer? it's not a standalone sentence because not all information is included.
C doesn't work because when does she wear her lucky shoes? We don't know.
B works. We have the subject and object, Cynthia and her shoes. It stands alone as its own sentence.
hope this helped :)
