Given below are two statements, one labelled as Assertion (A) and the other as Reason (R). **Assertion (A):** Unlike the Gandak, the Burhi Gandak river does not carry a massive, unmanageable silt load and has a relatively stable course. **Reason (R):** The Burhi Gandak originates from the spring-fed streams of the Someshwar Hills rather than snow-capped high Himalayan glaciers. Select the correct answer using the codes 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.
