I think the correct answer would be the third option. Environmental influences include family dynamics, neighborhood quality, and educational opportunities. These influences involve everything that surrounds an individual. The environment one is subjected to greatly affects the totality of that person may it be psychological, social, physical, behavior or attitude, beliefs and perception.
