To answer the question, let's analyze each option in relation to the documented research on television viewing:

A. Self-confidence: While television can have various effects on self-perception, there is no strong, consistent body of research that directly links television viewing to self-confidence in a significant way.

B. Leadership potential: There is no substantial evidence or well-documented research that suggests a direct link between television viewing and leadership potential.

C. Violence: Numerous studies have documented a link between television viewing and increased aggression or violent behavior, especially in children and adolescents. This is one of the most well-researched and widely accepted connections in the field of media studies.

D. Teen pregnancy: There is some research that suggests a correlation between exposure to sexual content on television and teen pregnancy rates. However, this link is not as extensively documented or universally accepted as the link between television viewing and violence.

Given the analysis, the most well-documented and widely accepted link is:

C. Violence

So, the correct answer is C. violence.
