The Minimum Support Price (MSP) is a mechanism used by governments to insure agricultural producers against any sharp fall in farm prices. Option 2, which includes barley, finger millet, groundnut, and sesamum, are all crops for which the MSP is announced.

To break it down further, here are explanations for each option:

Option 1 includes areca nut, barley, coffee, and turmeric. While the MSP is announced for barley as it`s a staple food, areca nut, coffee, and turmeric are mostly commercial crops and hence, are typically not supported with MSP.

Option 2 includes barley, finger millet, groundnut, and sesame. All of these crops are vital for India`s agricultural production and food security.

Option 3 includes areca nut, coffee, finger millet, groundnut, and sesame. Among these, the areca nut and coffee are excluded from the MSP, making this option incorrect.

Option 4 includes all the items except sesame, which is incorrect as the MSP is set for sesame as well. Thus, option 2 is the correct answer.
