Correct Answer: (b) Onam
Solution:Pookalam, also called Athapoo, is an intricate floral mat laid in the front courtyard by maidens of the house during Onam festival. It is the biggest and the most important festival of the state of Kerala.
It is a harvest festival, celebrated in the beginning of the month of Chingam, the first month of the Malayalam Calendar (Kollavarsham). The Onam lasts from four to ten days. First day, Atham and tenth day, Thiruonam are the most important of all. According to a popular legend, the festival is celebrated to welcome King Mahabali, whose spirit is said to visit Kerala at the time of Onam. Another key feature is Vallamkali, the Snake Boat Race, held on the river Pampa. Kaikotti kali and Thumbi Thullal are two graceful dances performed by women on Onam.
