B. Tungabhadra
C. Krishna
D. Tapti

Answer 1

Hint:: A rift valley refers to a lowland region that has formed when the earth’s tectonic plates move apart or rift. There is a river in India that flows through a rift parallel to the Narmada river.

Complete Answer:
A rift valley is formed on a divergent plate boundary, a crustal extension or the spreading part of a surface, which is further deepened by the forces of erosion. The Narmada, which is also called the Rewa, is a river situated in the central region of India and is also known as the fifth-longest river in the Indian subcontinent. The third longest river that flows inside India, after the Godavari and the Krishna River is Narmada. It is one of the three major rivers in peninsular India that runs in a direction from east to west, along with the Tapti River and the Mahi River. It flows in a rift valley. The Tapti River, a river in the central region, also flows through a rift valley in India. The river rises from the Gawilgarh Hills of the central Deccan plateau in the south-central state of Madhya Pradesh. It flows towards the west direction between two spurs of the Satpura range, across the Jalgaon plateau region in the state of Maharashtra, and through the plain of Surat in Gujarat to the Gulf of Khambhat which is an inlet of the Arabian Sea. The Tapti River flows parallel to the longer Narmada river to the north in which it is separated by the main part of the Satpura Range.
So, the correct answer is Option D.

Note: The three major tributaries of the Tapti river includes the Purna, the Girna, and Panjhra rivers which flows from the south in the state of Maharashtra. Also, Tapti flows parallel to the river Narmada. Another name of the Narmada river is Rewa.
