Given below are two statements, one labeled as Assertion (A) and the other labeled as Reason (R). **Assertion (A):** Shifting cultivation (Jhumming) leads to severe soil erosion, loss of biodiversity, and hydrological instability in the hilly regions of Northeast India. **Reason (R):** The shortening of the fallow cycle in shifting cultivation due to population pressure does not allow sufficient time for the forest and soil nutrients to regenerate. 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.
