Choice 'd' is correct. Baum should report $281,750 as 1999 net earnings from self-employment (line 12 of the Form 1040), calculated as follows:

Choices 'a', 'b', and 'c' are incorrect. Self-employment tax and self-employment health insurance expenses are adjustments from total gross income. They are not deducted from self-employment earnings (i.e., not reported net on line 12 of the Form 1040).

Note: There are many distracters in this question, all relating to items that are either deductible as part of itemized deductions or not deductible. Be careful to read the requirement of the question before spending unnecessary time on the question. The statement that Baum's year-end inventory was not subject to the uniform capitalization rules is a distracter as well. There is not enough information given in the facts to apply the rules if he had been subject to them.
