The correct option is (a) Both Statement-I and Statement-II are correct and Statement-II is the correct explanation for Statement-I.
The question addresses the relationship between Monetary Policy actions (specifically interest rate adjustments) and the primary objective of Central Banks, which is maintaining price stability (controlling inflation).
Statement-II provides the theoretical justification for the action described in Statement-I. Central Banks carried out interest rate hikes (Statement-I) precisely because they assume that such monetary policy measures are effective in controlling rising consumer prices (Statement-II). Thus, Statement-II explains Statement-I.
Key Takeaway: Central Banks utilize contractionary monetary policy (raising interest rates) to control inflation, based on the principle that higher borrowing costs reduce aggregate demand and cool down price pressures.
