The correct answer is C.
Rome was located in the middle of the Mediterranean sea, on its Northern shore. The city was founded in 753 BC.
Romans, at first, were not sailors at all but their privileged location made Rome a perfect stop for traders, and large exchanges started to occur there. When the Greek power started to decline, Rome and Carthage started to show important conflicts, and Rome copied Phoenician ships, building many of them in order to attack his enemy. In 241 BC Roman conquered Sicily, and afterwards Carthage in 146 BC.
Romans became the new dominators of the Mediterranean Sea, which they denominated the "Mare Nostrum", which means "our sea" in Latin.
