Final answer:
The Chola Kingdom succeeded by monopolizing trade through the Palk Strait, generating significant revenues. This allowed them to dominate trade in the Indian Ocean from about 970 to 1300.
Step-by-step explanation:
The kingdom that succeeded because of its ability to monopolize trade through the Palk Strait was the Chola Kingdom. The Chola Kingdom dominated trade in the Indian Ocean from about 970 to 1300, with control of the Palk Strait between Sri Lanka and southern India being crucial to their dominance. This strait served as a choke point where vessels had to stop and pay taxes, allowing the Chola Kingdom to generate enormous revenues from this trade monopoly.
