Given below are two statements, one labelled as Assertion (A) and the other labelled as **Reason (R):** Assertion (A):** The Narmada River has a highly asymmetrical basin, with most of its tributaries being very short and joining the main river at right angles. **Reason (R):** The Narmada flows through a narrow rift valley bounded by steep fault scarps of the Vindhyas and Satpuras, which restricts the development of a wide dendritic drainage network. Select the correct answer using the code given below:

Options:

• A: Both (A) and (R) are true and (R) is the correct explanation of (A)
• B: Both (A) and (R) are true but (R) is not the correct explanation of (A)
• C: (A) is true but (R) is false
• D: (A) is false but (R) is true
