The correct option is (a).
Explanation
The Tapi (or Tapti) is the second-largest west-flowing river of Peninsular India and flows through a rift valley parallel to the Narmada.
- Statement 1 is Correct: The Tapi river basin covers parts of Madhya Pradesh, Maharashtra, and Gujarat. The majority of the basin area lies in Maharashtra (approximately 79%), followed by Madhya Pradesh and Gujarat.
- Statement 2 is Incorrect: The Narmada is the longest west-flowing river in Peninsular India, with a length of approximately 1,312 km. The Tapi is significantly shorter, with a length of approximately 724 km.
- Statement 3 is Incorrect: The Tapi river originates near Multai in the Betul district of Madhya Pradesh in the Satpura range. It is the Narmada river that rises near the Amarkantak Plateau.
Key Takeaway: The Narmada and Tapi are the two major west-flowing rivers flowing through rift valleys. A crucial distinction is their origin: Narmada rises from Amarkantak, while Tapi rises from the Satpura range (Multai).
