Answer:
C. Jamie Foxx's newest movie were called The Soloist, which is based on a true story.
Explanation:
When checking for incorrectly written sentences, you should always check for spelling and subject-verb agreement (that the predicate and the subject of the same sentence have to be in the same number).
We can see the problem in answer C.
Subject of the sentence is Jamie Foxx's newest movie and the predicate is were called. Since the subject is in the third face singular, so it requires "was called" as a predicate.
