The correct way is to calculate the expected value. Since there is little data, the expected value is equal at base +30.000. The expected volatility is zero in case A and unknown but not zero in case B so a risk averse person would gain some utility out of going A.
Note however as both options are not a raise as the expected value is equal to her current salary and if person X accepts, she will be highlighted as an example of wage discrimination against women.
