D. Her standard deduction went up.

Step-by-step explanation:

We know that Julie changed her filing status from 'single' to 'head of household'.

Now, 'standard deduction' is the amount that is subtracted from the income before income tax is applied. It is based on the status of filing and differs for different status.

Now, the two filing status are single and head of household.

The 'head of household' status have many advantages as they receive a lower tax rate and higher standard deduction than the 'single' status.

So, when Julie changed her status from 'single' to 'head of household', her standard deduction will be higher.

Hence, option D is correct.
