Explanation:

- Option 1: Profitable

This refers to the condition when income from the sales exceeds the costs. It is a financial term, not specifically related to the portion sold.

- Option 2: Marketed Surplus

This is the correct term used for the portion of agricultural produce that a farmer sells after meeting his own needs. It reflects only the amount available for sale in the market.

- Option 3: Cost Surplus

This is not a commonly used term in agricultural economics. It is not the correct option for the given context.

- Option 4: None of the above

This would mean that none of the options are correct. However, since "Marketed Surplus" is indeed a correct term, this option does not apply.
