Given below are two statements, one labelled as Assertion (A), and the other labelled as Reason (R).
Assertion (A): In the medieval period the dam was as much an index of the value of copper, as the rupee was of silver. Interestingly the regional price variations attained a much greater importance in the case of copper metal than in that of gold or silver.
Reason (R): The main supplies were from the mines of the northern and eastern slopes of the Aravalli and the Vindhyan ranges. The proximity to these could play a large part in determining the extent of differences in price among various markets.
In the context of the above two statements which of the following is correct ?
1. Both (A) and (R) are true and (R) is the correct explanation of (A).
2. Both (A) and (R) are true, but (R) is not the correct explanation of (A).
3. (A) is true, but (R) is false.
4. (A) is false, but (R) is true.
