Which provision of the ACA helps young adults?

The provision of the Affordable Care Act that assists young adults is the one allowing them to remain on their parent's insurance plan. This provision is significant because it extends dependents' coverage up to the age of 26, regardless of their marital status, residency, or financial dependence on their parents. This has been particularly beneficial for young adults who may be entering the job market or pursuing higher education, as it provides them with immediate access to health insurance during a transitional period in their lives.

By allowing continued coverage, the ACA helps to reduce the uninsured rate among young adults, ensuring they have access to essential health services without the burden of high premiums that they might encounter on their own. This provision fosters greater stability in healthcare access for young people, which ultimately contributes to better health outcomes as they navigate the challenges of early adulthood.

The other options do not accurately represent supportive measures for young adults under the ACA, as the act does not end coverage for minors, does not intentionally increase healthcare costs for young adults, and does not restrict access to mental health services.
