Answer:
C). She is a well known basketball player.
Step-by-step explanation:
Punctuation is demonstrated as the defined conventional set of signs or symbols which primarily function to reflect the construction of the sentence and the manner in which it must be read that helps in clarifying the meaning.
As per the question, option C contains a punctuation error as the words 'well' and 'known' must involve a 'hyphen'(-) in between because the words together convey a single thought that is used to modify the noun 'basketball player'. The other options are correctly punctuated as the hyphen is correctly employed. Therefore, option C is the correct answer.
