Answer:
Answer is Option B: Defeating the Carthaginians, The Romans established control over the Mediterranean Sea.
Step-by-step explanation:
Punic wars were three wars fought between Rome and Carthage. Rome won all the three wars. They therefore became one of the dominant military powers in the Mediterranean Sea.
Carthage was destroyed by the Roman Empire. In the second war, Rome punished Macedonia for his intervention from Carthage's side. They conquered the eastern Mediterranean then. The surviving Carthage's citizens were sold into slavery. Soon after their victory, they spread their influence outside Italy.
Thus, Option B is the statement describing the significance of Punic wars.
