Final answer:
Option D, the supposed differences in abilities between males and females, is not a cause of workforce composition issues at technology companies; societal factors and discrimination practices contribute to the gender gap in tech fields.
Step-by-step explanation:
The question pertains to the factors contributing to workforce composition issues at technology companies. Among the provided options, D) Difference in abilities between males and females is not a cause of these issues. There is no evidence to suggest intrinsic differences in abilities between genders; rather, societal factors such as gender stereotypes, patterns in studying STEM subjects, and unconscious biases contribute significantly to these composition issues. The 'glass ceiling', patterns in education, and media portrayal reinforce these stereotypes and discourage equitable participation in tech fields. Additionally, discriminatory practices, though often covert and subtle, continue to exist and contribute to the gender gap and pay disparities.
