Final answer:

Step-by-step explanation:
Guaranteed Issue Window for Medicare Supplement Plans
The Guaranteed Issue window time period for Medicare Supplement (Medigap) plans is C) the six months following one's 65th birthday.
During this timeframe, individuals who are turning 65 and are enrolled in Medicare Part B are given guaranteed rights to buy a Medigap policy regardless of their health status.
This means that insurance companies cannot use medical underwriting to deny coverage, impose a waiting period for pre-existing conditions, or charge higher premiums due to past or present health conditions.
Outside of this Guaranteed Issue period, individuals may still apply for Medigap coverage, but insurance companies are allowed to use medical underwriting to decide whether to accept the application and how much to charge the individual for the Medigap policy.
Reflecting upon the program's history, Medicare was part of the Social Security Act of 1965, aimed at providing federal health insurance primarily for individuals who are 65 and older, which covered around 40 million people at that time.
In terms of political influence, elderly Americans have proven to be a significant interest group, donating money and time to political campaigns, and showing a strong voter turnout in elections, with a notable difference compared to the younger demographics.
