Given below are two statements, one labeled as Assertion (A) and the other as Reason (R). **Assertion (A):** The Tal soils of South Bihar remain completely submerged under water during the monsoon season, making Kharif cultivation impossible. **Reason (R):** Tal soils are situated in low-lying backwater depressions formed behind the natural levees of the Ganges River. 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
