Which of the following statements is true regarding 529 plans?

Qualified distributions from a 529 plan are federal income tax-free when used for qualified education expenses. These plans are municipal fund securities designed to help families save for education. Qualified expenses may include tuition, certain fees, books, supplies, and room and board when applicable requirements are satisfied. Choice A is correct. Choice B is incorrect because 529 tax treatment is based on qualified education use, not the beneficiary reaching age 65. Choice C is incorrect because medical emergencies are not the standard qualified education use for 529 distributions. Choice D is incorrect because a 529 plan is not generally rolled into a traditional IRA; the traditional SIE concept is that 529 assets must be used for permitted education-related purposes to receive favorable tax treatment. The SIE outline identifies 529 plans under municipal fund securities and requires knowledge of owner versus beneficiary, restricted use of plan assets, tax advantages, and direct or adviser-sold plans. The core exam point is that the tax benefit is conditional: withdrawals used for qualified education expenses receive favorable federal tax treatment.
