The correct answer is: a) Travancore Dynasty.
The Padmanabhaswamy Temple is a Hindu temple dedicated to Vishnu, located in Thiruvananthapuram, Kerala, India. It is one of the most famous temples in India and is closely associated with the Travancore Dynasty. The temple was built in the 16th century by the Travancore kings and is considered to be one of the richest temples in India. The temple is also known for its intricate architecture and sculptures.
The Chera Dynasty was a major power in South India from the 3rd century BCE to the 12th century CE. The Zamorins were a powerful dynasty that ruled the Malabar Coast from the 14th century to the 18th century. The Venad Kingdom was a small kingdom that ruled the area around Thiruvananthapuram from the 8th century to the 16th century.
The Padmanabhaswamy Temple is not closely associated with the Chera Dynasty, the Zamorins, or the Venad Kingdom. It is closely associated with the Travancore Dynasty, who built the temple and ruled the area around Thiruvananthapuram for centuries.
