Given below are two statements, one labeled as Assertion (A) and the other labeled as Reason (R). **Assertion (A):** Pastoralism remained a vital component of the Harappan economy alongside intensive urban agriculture. **Reason (R):** The maintenance of large herds of cattle, sheep, and goats required seasonal transhumance to exploit grazing lands outside the active agricultural zones. In the context of the above statements, which of the following is correct?

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.
