Final answer:
The correct answer is c) Once a year during open enrollment.
Step-by-step explanation:
With typical individual protection plans, you can enroll only once a year during open enrollment. Open enrollment is a specific period of time when individuals can sign up for or make changes to their healthcare coverage. Outside of this period, individuals may only enroll in a plan if they experience a qualifying life event, such as getting married, having a baby, or losing existing coverage.
For example, if you have a job that offers health insurance, you typically have a designated period, usually in the fall, when you can choose your coverage for the following year. During this open enrollment period, you can select a plan that best fits your needs and make changes to your existing coverage.
