Which sentence uses possessive personal pronouns correctly A Was that sandwich his or hers B That car with the tinted windows is our's C Yours bicycle will be repaired by Friday?

A. "Was that sandwich his or hers?"

The possessive pronouns 'his or hers' take the place of the noun 'sandwich'.

B. The possessive pronoun our's is incorrect; possessive pronouns do not use an apostrophe.

C. The possessive pronoun yours is used incorrectly; the possessive adjective your should be placed before a noun to describe the noun (bicycle).
