The answer is A. I got it wrong. The explanation is crazy.
The interest income (nonbusiness income) is offset by nonbusiness expenses, up to the amount of nonbusiness income. The standard deduction is a nonbusiness expense for this purpose.
IRC Section 172(d)(4)
The net capital loss (nonbusiness) is only deductible to the extent it is offset by nonbusiness capital gains.
IRC Section 172(d)(2)
Personal exemptions and unused personal deductions are added back to taxable income in arriving at net operating losses so they do not increase the carryback or carryforward.
The net business loss must be offset by wages and rental income for this year.
IRC Section 172
Wages of $5,000 plus net rental income of $4,000 minus the loss of $16,000 equals a net operating loss carryback or carryforward of $7,000.
