The correct answer is (b), Shaiva and Shakta sect.
Shaivism and Shaktism are two of the major Hindu sects. Shaivism is the worship of Shiva, one of the principal deities of Hinduism. Shaktism is the worship of Shakti, the divine feminine principle. Both Shaivism and Shaktism have a long and rich history in India, and they continue to be practiced by millions of Hindus today.
In Uttarakhand, Shaivism and Shaktism are the two most popular sects. The state is home to many important Hindu temples, including the Kedarnath Temple, the Badrinath Temple, and the Gangotri Temple. These temples are all dedicated to Shiva, and they attract pilgrims from all over India.
Shaivism and Shaktism are also popular in the Kumaon region of Uttarakhand. The Kumaon region is home to many important Shakta temples, including the Jageshwar Temple and the Dhumavati Temple. These temples are dedicated to Shakti, and they attract pilgrims from all over India.
Shaivism and Shaktism have a deep rooted impact on the masses of Uttarakhand. The two sects have shaped the culture and religion of the state for centuries. They continue to be practiced by millions of Hindus today, and they play an important role in the lives of the people of Uttarakhand.
