Final Answer : A, Explanation :  Research indicates that biological factors, including genetic, hormonal, and brain structure differences, have a more significant influence on sexual orientation than environmental factors. Studies of twins, for example, show higher concordance rates for sexual orientation among identical twins than among fraternal twins, suggesting a genetic component. Additionally, differences in brain structure and function have been observed between heterosexual and homosexual individuals. While environmental factors may also play a role, the evidence for biological influences is stronger and more consistent.
