Research Has Demonstrated What About the Capacities of Young, Pre-Pubertal

Research has demonstrated what about the capacities of young, pre-pubertal children to develop stable transgender identities?

A) Most children do not have an understanding of gender that is nuanced enough to identify a lack of fit between their felt and assigned gender category.
B) Even at a young age, children may develop a clear and consistent sense of themselves as belonging to a gender group that differs from their assigned sex.
C) While young children may identify that their assigned gender does not fit their experiences, they lack the cognitive resources to maintain a stable transgender identity.
D) Children's gender identity is determined entirely by feedback from their parents and authority figures.
