The correct answer is: B) Megalithic burial complex.
Kodumanal is a megalithic burial complex located in the Madurai district of Tamil Nadu, India. It is one of the largest and most important megalithic sites in India, and is dated to the Iron Age. The site consists of over 1,000 megalithic burials, which are made up of large stones arranged in various shapes and sizes. The burials are believed to have been used for the interment of important individuals, and may have been associated with religious or ritual practices.
The other options are incorrect because:
- A) Paleolithic cave sites are associated with the earliest humans, who lived during the Paleolithic period. Kodumanal is not a Paleolithic cave site.
- C) Sangam Age trade centers were important trading hubs during the Sangam period, which lasted from around 300 BCE to 300 CE. Kodumanal is not a Sangam Age trade center.
- D) Medieval ports were important trading hubs during the medieval period. Kodumanal is not a medieval port.
