Final answer:
The correct answer is Brandon's.
Step-by-step explanation:
The correct answer is c. Brandon's.
When indicating possession in English, we typically use an apostrophe followed by an 's'. In this case, we are referring to a new sweater belonging to Brandon. Therefore, we need to use the possessive form of Brandon, which is Brandon's.
For example, if we were talking about a new book belonging to Emily, we would say 'Emily's book.'
