Answer:
Natassia's belief is best described as an example of the gender perspective.
Step-by-step explanation:
In sociology, the gender perspective studies the implications and meaning of being a man or a women in a specific society and in a certain time frame. These gender differences begin at a very early age, the gender perspective states that we learn how to be a man or how to be a woman due to early gender socialization; in this sense, Natassia's explanation to why boys tend to behave more aggressively than girls is an example of a gender perspective study.
