Marginalism and Optimization

Most of the microeconomic models hinge on suppositions that all choices by each and every individual imitate attempts to: (1) Conform to social mores and cultural norms. (2) Propagate the individual’s gene pool into the future generations. (3) Balance the predicted personal marginal advantages of each and every activity with its predicted personal marginal costs. (4) Maximize accounting gains and minimize losses. (5) Achieve status, class and power.

Can someone please help me in finding out the accurate answer from the above options.
