Final answer:
Wessel and Antoinette should seek a health insurance plan through their state's marketplace exchange where they are eligible for premium assistance under the ACA, given their income is at 133 percent of the federal poverty level.
Step-by-step explanation:
Wessel and Antoinette, whose combined income is 133 percent of the federal poverty level, are in search of health care coverage as they expect the birth of their first child. The Affordable Care Act (ACA) provides a solution by offering premium assistance to help pay for health insurance. Since their income is within the threshold of eligibility, they can apply for subsidized coverage through their state's marketplace exchange.
This subsidy will significantly lower the cost of their premiums, making health insurance more affordable for them. Additionally, the ACA ensures that they cannot be denied coverage due to any pre-existing conditions and covers a wide range of essential health benefits, which is especially important for expectant parents. Therefore, the best purchase option for them would be a subsidized health insurance plan from their state's marketplace exchange, tailored to their income level.
