The correct answer is option 'A': 1 only.
Explanation:
The Narmada River is one of the major rivers in India. Let's analyze each statement given in the question separately to determine their correctness:
1) It is the largest west-flowing river in peninsular India.
The Narmada River is indeed the largest west-flowing river in peninsular India. It originates from the Amarkantak Plateau in Madhya Pradesh and flows in a westward direction before draining into the Arabian Sea. The river has a total length of approximately 1,312 kilometers and traverses through the states of Madhya Pradesh, Maharashtra, and Gujarat. The statement is correct.
2) It flows through five states in India.
This statement is incorrect. The Narmada River flows through three states in India, namely Madhya Pradesh, Maharashtra, and Gujarat. It does not pass through five states. Therefore, statement 2 is incorrect.
In conclusion, only statement 1 is correct. The Narmada River is the largest west-flowing river in peninsular India, but it flows through three states, not five.
