Answer:
The correct answer is <u>C</u>: Yesterday, the Star Tribune published an article about pigs living in southern France, near the Mediterranean Sea.
Explanation:
Yesterday – it must be capitalized, as it is <u>the first word of the sentence</u>.
<em></em>
Star Tribune – it’s<u> a proper noun</u>, that is, a full name of newspapers, so it must be capitalized.
southern France – <em>southern</em><em> </em>is a descriptive term we use to denote a direction or a position. It is not a proper name, so it should not be capitalized. However, France is a proper noun and we should write it with a capital "F" because it is the name of a specific country.
