The major rivers flowing through Tamil Nadu include:

Kaveri, Vaigai, Palar
Krishna, Godavari, Narmada
Ganga, Brahmaputra, Mahanadi
Sutlej, Beas, Ravi

The correct answer is: a) Kaveri, Vaigai, Palar.

The Kaveri is the longest river in Tamil Nadu, flowing through the state from north to south. The Vaigai is a major river in the central part of Tamil Nadu, while the Palar is a river in the northern part of the state.

The Krishna, Godavari, and Narmada are all major rivers in India, but they do not flow through Tamil Nadu. The Ganga, Brahmaputra, and Mahanadi are also major rivers in India, but they are located in the northern part of the country, far from Tamil Nadu.

The Sutlej, Beas, and Ravi are all rivers in the Punjab region of India. They do not flow through Tamil Nadu.
