Which of the following statements are CORRECT when comparing For AGI deductions to From AGI deductions?

Deduction for AGI reduces AGI thus reducing the limitations on other tax benefits that are decreased or phased out for higher-income taxpayers.

For AGI deductions are also called deductions "below the line" or "itemized deductions."

For AGI deductions are subtracted directly from adjusted gross income.

From AGI deductions are generally preferred over deductions for AGI.

Certain from AGI deductions may not have an effect on taxable income despite the taxpayer incurring the expense.
