Statement B is true because male fetuses have a higher rate of miscarriage than female fetuses due to genetic abnormalities and developmental issues. Statement C is true because there are cultural and governmental policies in some societies that prefer male children over females, leading to the possibility of selective abortion and limiting access to education and resources for female children. Statement A is not entirely true as sperm with Y chromosome may have a higher motility, but it is not significantly different from sperm with X chromosome in terms of swimming speed.
