Ten-Year-Old David Has Been Spending a Lot of Time Reading

Ten-year-old David has been spending a lot of time reading fashion magazines and making clothes for his dolls. He prefers celebrity gossip with his sisters to playing sniper videogames with his brother. David's parents worry that such behaviour might mean that he will grow up to be gay, but their friend says such thinking is just an ugly stereotype. Who's right?

A) There is anecdotal evidence that many males who display highly effeminate behaviour in childhood later experience same-sex attraction, but it has not been proven in research.
B) Research supports that many males who display highly effeminate behaviour in childhood later experience same-sex attraction.
C) Research is inconclusive whether a boy's highly effeminate behaviour in childhood will result in experiencing same-sex attraction later in life.
D) Extensive research shows beyond doubt that boys' childhood behaviour has no reflection in their later sexual/affectational orientation.
