Final answer:
Television and movies are significant gender influences outside of parental impact, often reinforcing traditional gender roles and behavior through the characters and stories portrayed.
Step-by-step explanation:
Other than parents, one of the most powerful gender influences is D. television and movies. This is evident from research indicating how mass media serves as an agent of gender socialization. Women often have less significant roles in media, generally portrayed as wives or mothers. When lead roles are offered, they tend to fall into stereotypical figures. This portrayal reinforces gender roles and shapes the public's perceptions of gender-specific behavior. Such consistent exposure to gender norms in media leads individuals to absorb and enact these roles, sometimes under the misconception that they are natural behaviors rather than socially constructed roles.
