Final answer:
A college sports participant, or a popular late-night talk show host is known as Host, because it refers to those who lead late-night entertainment or talk show formats. So, option b. Host is correct.
Step-by-step explanation:
A host in the context of television refers to an individual who leads or presents shows, particularly in late-night entertainment or talk show formats.
It is crucial to clarify that this definition is distinct from a college sports participant, who is typically referred to as a 'player' in sports contexts.
The given reference materials may not explicitly address the question, but an understanding of common terminology in media and sports allows for a deduction that is 'Host.'
Late-night hosts, exemplified by figures like Stephen Colbert and Jon Stewart, play influential roles in shaping public opinion and political discourse through television.
Their significance extends beyond mere entertainment, making them key figures in the media landscape with the ability to impact societal perspectives and discussions.
Hence, the option b. Host is correct.
