Answer:The provision included in the Affordable Care Act are:
1. Young adults can be covered by their parents' health insurance through age 26.
This provision allows young adults to remain on their parents' health insurance plan until they reach the age of 26, even if they are no longer living with their parents or are financially independent.
This provision has been beneficial for many young adults who may be starting their careers or attending school and do not have access to employer-sponsored health insurance.
The other options mentioned in the question are not provisions of the Affordable Care Act. Insurance companies are actually prohibited from denying coverage based on pre-existing conditions, thanks to the ACA, and they cannot arbitrarily stop insuring customers without valid reasons under the law.
